An enhanced self-similar pulse compression with suspended core photonic crystal fiber has been theoretically studied. The proposed model well support the essential criteria of having very low dispersion and increased nonlinearity with increasing suspension factor resulting high compression rate within short length of the fiber. Unlike the conventional tapering methods, the suspended core photonic crystal fiber can achieve the self-similar conditions more easily and reduces the practical difficulties to achieve the desired fiber parametric values. We have also studied the possible deformations of the fiber and temperature variations that can effect the pulse compression process and compression factor.

To better understand the real-time biomechanics of soft tissues under sudden mechanical loads such as traumatic spinal cord injury (SCI), it is important to improve in vitro models. During a traumatic SCI, the spinal cord suffers high-velocity compression. The evaluation of spinal canal occlusion with a sensor is required in order to investigate the degree of spinal compression and the fast biomechanical processes involved. Unfortunately, available techniques suffer with drawbacks such as the inability to measure transverse compression and impractically large response times. In this work, an optical pressure sensing scheme based on a fiber Bragg grating and a narrow-band filter was designed to detect and demonstrate the transverse compression inside a spinal cord surrogate in real-time. The response time of the proposed scheme was 20 microseconds; a five orders of magnitude enhancement over comparable schemes that depend on costly and slower optical spectral analyzers. We further showed that this improvement in speed comes with a negligible loss in sensitivity. This study is another step towards better understanding the complex biomechanics involved during a traumatic SCI, using a method capable of probing the related internal strains with high-spatiotemporal resolution.

The stable propagation of orbital angular momentum and cylindrical vector beams in a newly designed annular core photonic crystal fiber (AC-PCF) tailored for the broadband single-radial order beam transmission (within the so-called “endlessly mono-radial” guiding regime) is demonstrated for the first time. It is shown that the vector-vortex beams can maintain high mode purities above 18 dB after propagation in the fiber under test over all of the wavelength range from 805 to 845 nm (over 17 THz bandwidth) investigated with the help of a tunable laser and an S-plate for the generation of singular beams in free space. Our results confirm that the AC-PCF is a promising design for the broadband transmission of vector-vortex beams that have potential applications in space-division multiplexing, quantum communications, optical sensing and trapping.

An optical setup was devised for the Electrical engineering undergraduate course “Photonic devices” where students were introduced to a simple visible diode laser based method of measuring the refractive indices of liquid samples in a transparent quartz cuvette placed on a computer-controlled rotating stage. When setting the cuvette at a small angle with respect to the incident laser beam, the light transmission through the cuvette results in a small mm-scale deflection of the laser path. The evaluation of the sample’s refractive index hinges on measuring the beam displacement. Moreover, by positioning the cuvette at normal incidence and recording the optical power after passing through various liquid samples (e.g. distilled water, maple syrup) and comparing with a reference (empty cuvette), students learn to estimate the attenuation coefficients of the substances by taking into account the contribution of the multiple Fresnel reflections. Finally, the same optical setup is also used by students to perform the “knife-edge” technique for the characterization of the beam profile emitted by the visible diode laser used in the setup. The proposed setup was implemented in the fall 2018 where undergraduate students were able to practice optical alignment and implement the concepts of material refractive indices and attenuation, as well as revisit the Gaussian beam theory taught in-class.

We demonstrate a new guiding regime termed endlessly mono-radial, in the proposed annular core photonic crystal fiber (AC-PCF), whereby only modes of the fundamental radial order are supported by the fiber at all input wavelengths. This attribute is of high interest for applications that require the stable and broadband guiding of mono-radial (i.e. doughnut shaped) cylindrical vector beams and vortex beams carrying orbital angular momentum. We further show that one can significantly tailor the chromatic dispersion and optical nonlinearities of the waveguide through proper optimization of the photonic crystal microstructured cladding. The analytical investigation of the remarkable modal properties of the AC-PCF is validated by full-vector simulations. As an example, we performed simulations of the nonlinear fiber propagation of short femtosecond pulses at 835 nm center wavelength and kilowatt-level peak power, which indicate that the AC-PCF represents a promising avenue to investigate the supercontinuum generation of optical vortex light. The proposed fiber design has potential applications in space-division multiplexing, optical sensing and super-resolution microscopy.

We propose the generation of high-purity perfect cylindrical vector beams (PCVB) using the Fourier transformation of Bessel-Gauss vector beams. The demonstration of PCVBs is implemented via an interferometric method employing a spatial light modulator that allows a fully independent control of the ring diameter (RD ) and ring width (RW) of the PCVB. The proposed scheme enables to generate different types of cylindrical vector beams with precise user-defined transverse dimensions. The dynamic control of the ring width, ring diameter, and the specific type of PCVBs desired is theoretically as well as experimentally demonstrated. The proposed experimental setup can not only be employed in the generation of arbitrary PCVB, but also in perfect vortex beams. The ability to generate fully tailorable cylindrical vector beams and vortex beams has implications for the efficient launch of exotic optical modes in specialty fibers, in the field of optical tweezers as well as for superresolution microscopy.

In vitro replication of traumatic spinal cord injury is necessary to understand its biomechanics and to improve animal models. During a traumatic spinal cord injury, the spinal cord withstands an impaction at high velocity. In order to fully assess the impaction, the use of spinal canal occlusion sensor is necessary. A physical spinal cord surrogate is also often used to simulate the presence of the spinal cord and its surrounding structures. In this study, an instrumented physical spinal cord surrogate is presented and validated. The sensing is based on light transmission loss observed in embedded bare optical fibers subjected to bending. The instrumented surrogate exhibits similar mechanical properties under static compression compared to fresh porcine spinal cords. The instrumented surrogate has a compression sensing threshold of 40% that matches the smallest compression values leading to neurological injuries. The signal obtained from the sensor allows calculating the compression of the spinal cord surrogate with a maximum of 5% deviation. Excellent repeatability was also observed under repetitive loading. The proposed instrumented spinal cord surrogate is promising with satisfying mechanical properties and good sensing capability. It is the first attempt at proposing a method to assess the internal loads sustained by the spinal cord during a traumatic injury.

In this work, we demonstrate the measurement of the Brillouin gain spectra of vector modes in a few-mode fiber for the first time using a simple heterodyne detection technique. A tunable long period fiber grating is used to selectively excite the vector modes supported by the few-mode fiber. Further, we demonstrate the non-destructive measurement of the absolute effective refractive indices (n eff ) of vector modes with ~10−4 accuracy based on the acquired Brillouin frequency shifts of the modes. The proposed technique represents a new tool for probing and controlling vector modes as well as modes carrying orbital angular momentum in optical fibers with potential applications in advanced optical communications and multi-parameter fiber-optic sensing.

We directly measure the spatially and spectrally resolved gain of erbium doped multicore and few mode fiber amplifiers using a coherent swept wavelength interferometer operated in the reflection mode. It greatly simplifies the characterization of multispatial mode amplifiers because it enables characterization of the mode-dependent gain with only a single mode-selective multiplexer at the input. The gains for both multicore fiber amplifier and three spatial modes (LP01 and ${\rm{LP}}_{{11}}$) amplifier are measured. Measurements for multicore fiber amplifier are conducted using two pump schemes, core pump and cladding pump. Also, the comparison with the cutback experiments shows the validity of this technique.

We propose and numerically investigate annular-cladding erbium doped multicore fibers (AC-EDMCF) with either solid or air hole inner cladding to enhance the pump power efficiency in optical amplifiers for spatial division multiplexing (SDM) transmission links. We first propose an all-glass fiber in which a central inner cladding region with a depressed refractive index is introduced to confine the pump inside a ring-shaped region overlapping the multiple signal cores. Through numerical simulations, we determine signal core and annular pump cladding parameters respecting fabrication constraints. We also propose and examine a multi-spot injection scheme for launching the pump in the annular cladding. With this all-glass fiber with annular cladding, our results predict 10 dB increase in gain and 21% pump power savings compared to the standard double cladding design. We also investigate a fiber with an air hole inner cladding to further enhance the pump power confinement and minimize power leaking into the inner cladding. The results are compared to the all-glass AC-EDMCF.

The ability to integrate multiple materials into miniaturized fiber structures enables the realization of novel biomedical textile devices with higher-level functionalities and minimally-invasive attributes. In this work, we present novel textile fabrics integrating unobtrusive multi-material fibers that communicate through 2.4 GHz wireless networks with excellent signal quality. The conductor elements of the textiles are embedded within the fibers themselves, providing electrical and chemical shielding against the environment, while preserving the mechanical and cosmetic properties of the garments. These multi-material fibers combine insulating and conducting materials into a well-defined geometry, and represent a cost-effective and minimally-invasive approach to sensor fabrics and bio-sensing textiles connected in real time to mobile communications infrastructures, suitable for a variety of health and life science applications.

Design tools have existed for decades for standard step-index fibers, with analytical expressions for cutoff conditions as a function of core size, refractive indexes, and wavelength. We present analytical expressions for cutoff conditions for fibers with a ring-shaped propagation region. We validate our analytical expressions against numerical solutions, as well as via asymptotic analysis yielding the existing solutions for standard step-index fiber. We demonstrate the utility of our solutions for optimizing fibers supporting specific eigenmode behaviors of interest for spatial division multiplexing. In particular, we address large mode separation for orbital angular momentum modes and fibers supporting only modes with a single intensity ring.
