We present new type of silica graded index laser-optimized multimode optical fibers (LOMF) with extremely enlarged core diameter up to 100 μm and “typical” “telecommunication” cladding diameter 125 μm. This optical fiber was designed for harsh environment Gigabit onboard cable systems and industrial networks. It differs by special optimized graded refractive index profile, providing low differential mode delay (DMD) for selected guided modes. We present some results of tests, performed for manufactured pilot 520 m length of described LOMF 100/125, concerned with its geometry properties as well as key transmission parameters—attenuation and DMD map.

This work presents an alternative method implemented in software procedure for automated localization of fiber optic connector contaminated ferrule end face image artifacts. Here the main problem is concerned with detection and removing the aureoles of core/cladding and cladding/ferrule boundaries without impact on pixels of contamination particles. We considered typical end face images measured by commercially available fiber optic video probe kit containing video microscope and software, which provides ferrule end-face quality inspection "PASS/FAIL" according to ratified standard IEC 61300-3-35 that is a global common set of quality requirements for the surface of ferrule fiber optic connectors. After removing artifacts, modified image may be utilized for the following estimation of the predicted value of insertion loss. We also present some results of proposed procedure approbation for various order contaminated ferrule end face images.

This work presents results of experimental approbation of earlier on proposed modified fiber optic stress sensor based on a few-mode effects occurring during laser-excited optical signal propagation over silica multimode optical fiber (MMF). Modification is concerned with a passage to quasi-interferometric scheme realized by two multimode Y-couplers with equalized arm lengths improved by fiber Bragg grating (FBG) written on preliminary formed precision macrostructure defects in silica multimode graded-index optical fibers and special offset launching conditions providing laser-based excitation of higher-order modes. The “arms” of quasi-interferometer are two equalized lengths of MMF Cat. OM2 with great central dip of refractive index profile and strong pulse splitting due to high differential mode delay (DMD). We tested FBGs with Bragg wavelength both 1310 nm and 1550 nm written over tapers or up-tapers preliminary formed in short pieces of MMF Cat. OM2+/OM3 and further jointed to the end of one of the arms before output Y-coupler. Researches were focused on comparison analysis of pulse responses under changing of selected excited mode mixing and power diffusion processes due to stress distributed action to sensor fiber depending. Here we considered FBGs not only as particular wavelength reflector during spectral response measurement but also as local periodic microstructure defect which strongly effects on few-mode signal components mixing process also improved by combination with macro-defect like taper or up-taper that should provide response variation. Some results pulse response measurements produced for different scheme configuration and their comparison analysis are represented. © (2017) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).

This work presents method for performing precision macro-structure defects “tapers” and “up-tapers” written in conventional silica telecommunication multimode optical fibers by commercially available field fusion splicer with modified software settings and following writing fiber Bragg gratings over or near them. We developed technique for macrodefect geometry parameters estimation via analysis of photo-image performed after defect writing and displayed on fusion splicer screen. Some research results of defect geometry dependence on fusion current and fusion time values re-set in splicer program are represented that provided ability to choose their “the best” combination. Also experimental statistical researches concerned with “taper” and “up-taper” diameter stability as well as their insertion loss values during their writing under fixed corrected splicer program parameters were performed. We developed technique for FBG writing over or near macro-structure defect. Some results of spectral response measurements produced for short-length samples of multimode optical fiber with fiber Bragg gratings written over and near macro-defects prepared by using proposed technique are presented. © (2017) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).

This work is concerned with fiber Bragg grating (FBG) writing technique developed for graded-index multimode optical fibers applied in measurement systems based on a few-mode effects. We present some results of experimental approbation of proposed technique with Bragg wavelength 1310 and 1550 nm on samples of graded-index multimode optical fibers 50/125 of both new-generations Cat. OM2+/OM3 and old Cat. OM2 with preliminary measured refractive index profiles. While the first group fibers of Cat. OM2+/OM3 was characterized by almost ideal smooth graded refractive index profile and some fiber profile samples of this group contains thin central peak, the second fiber group profiles of Cat. OM2 differ by great central core defects representing dip or thick peak.

This paper presents a microwave photonics method for the instantaneous frequency measurement of microwave signals, based on the generation of a two-frequency laser radiation in the Mach-Zehnder modulator with a difference frequency equal to the measured, and the "frequency - amplitude" conversion in the π-phase-shifted fiber Bragg grating. Frequency measurement occurs in two ranges: 0.3 - 3 GHz in the passband of the FBG and 3 - 30 GHz in its reflection band. Using the specific conversion of two-frequency radiation in the π-phase-shifted fiber Bragg grating allowed us to obtain measuring characteristics, that are independent of the amplitude fluctuations of the optical carrier and to organize additional circuit for monitoring the spectral characteristics of the used elements to reduce measurement inaccuracy caused by their temperature instability.

This paper presents a new two-frequency method for the instantaneous frequency and amplitude measurement of unknown microwave signal. Using the specific interaction of two-frequency radiation with fiber Bragg grating (FBG) in first version and FBG with phase π-shift in second allowed us to obtain measuring characteristics, that are independent of the energy fluctuations of the optical carrier and the microwave signal. Frequency measurement occurs in two ranges: 3-30 GHz in FBG reflection band, and in second version 0,3-3 GHz in the FBG pass band. Additional circuit for spectral characteristics monitoring of the used elements are organized to reduce measurement inaccuracy caused by their temperature instability.
