Critical slowing down near a bifurcation or limit point leads to a dynamical hysteresis that cannot be avoided by sweeping a control parameter slowly through the critical point. This paper analytically illustrates, with the help of a simple model, the bifurcation shift. We describe an inexpensive experiment using a semiconductor laser where this phenomenon occurs near the threshold of a semiconductor laser.

Jesper MoerkGian Luca LippiRate equations for micro- and nanocavity lasers are formulated which take account of the finite number of emitters, Purcell effects as well as stochastic effects of spontaneous emission quantum noise. Analytical results are derived for the intensity noise and intensity correlation properties, g(2), using a Langevin approach and are compared with simulations using a stochastic approach avoiding the mean-field approximation of the rate equations. Good agreement between the two approaches is found even for large values of the spontaneous emission beta-factor, i.e., for threshold-less lasers, as long as more than about ten emitters contribute to lasing. A large value of the beta-factor improves the noise properties.

We provide a comprehensive analysis of the standard model of the bidirectional ring laser in which only one mode can be supported in each direction and in the limit that the polarization can be eliminated adiabatically. The interaction between the two counterpropagating modes can be derived and it is most naturally viewed as a coupling between them via scattering from a spatial grating formed in the population inversion. If the grating is a sufficiently small modulation of the spatial average of the population inversion, it can be approximated by a sinusoidal function. A systematic derivation of the model with only a sinusoidal grating for the homogeneously broadened case is presented that reveals and corrects errors in several previously published analyses. The stability of the steady-state solution is analyzed. The bidirectional steady-state solution is unstable and the unidirectional steady-state solutions may be stable or unstable depending on the parameters. The well-established result of bistability between the two modes when the cavity is tuned to resonance is recovered, a result that persists, in part, even when the losses between the two modes are different.

Gian Luca LippiA Stochastic Simulator (SS) is proposed, based on a semiclassical description of the radiation-matter interaction, to obtain an efficient description of the lasing transition for devices ranging from the nanolaser to the traditional “macroscopic” laser. Steady-state predictions obtained with the SS agree both with more traditional laser modeling and with the description of phase transitions in small-sized systems, and provide additional information on fluctuations. Dynamical information can easily be obtained, with good computing time efficiency, which convincingly highlights the role of fluctuations at threshold.
About Me
Gian Luca Lippi received a Laurea degree in Fisica from the University of Florence, Italy, in 1984, a Ph.D. degree from Bryn Mawr College, USA, in 1990, and a Habilitation degree from the Université de Nice-Sophia Antipolis, France, in 1998. He is a Distinguished Professor in the Physics Department, Université Côte d’Azur (UCA). Since 1994, he has been a member of the Institut de Physique de Nice (formerly Institut Non Linéaire de Nice). From 1990 to 1993, he was an active Postdoctoral Fellow with the Institut für Angewandte Physik (Westfälische Wilhelms-Universität Münster, Germany) first as Alexander-von Humboldt Fellow, then with DFG support. He has authored and co-authored over 80 articles in refereed journals, 25 conference proceedings, and more than 150 contributions to conferences (45 invited presentations). His research covers laser dynamics, nonlinear dynamics in optical systems, laser-matter interactions, particle trapping, physical properties of nanolasers, and biophotonics mainly from an experimental point of view but including modeling aspects. He has been the Director of the French Doctoral School in Sciences and the European Doctorate EDEMOM, a Former International Consultant for the Project Laser Trapped Mirror Proposal (MSMT, NASA), a past Referee for INTAS (EU) and EPSRC (U.K.) programs, and a referee for all the main physics journals. He is currently a member of the Scientific Council of the Academy 4 at UCA and Co-Chair of LPHYs (Seminar 4).
