Item Bistability and Hysteresis in an Optically Injected Two-Section Semiconductor Laser(Amer Physical Soc, 2014-05-08) Pimenov, A.; Viktorov, E. A.; Hegarty, S. P.; Habruseva, T.; Huyet, G.; Rachinskii, Dmitry I.; Vladimirov, A. G.; 0000 0003 5341 0057 (Rachinskii, DI); Rachinskii, Dmitry I.The effect of coherent single frequency injection on two-section semiconductor lasers is studied numerically using a model based on a set of delay differential equations. The existence of bistability between different continuous-wave and nonstationary regimes of operation is demonstrated in the case of sufficiently large linewidth enhancement factors.Item Effect of Dynamical Instability on Timing Jitter in Passively Mode-Locked Quantum-Dot Lasers(Optical Soc Amer, 2014-12-08) Pimenov, A.; Habruseva, T.; Rachinskii, Dmitry I.; Hegarty, S. P.; Huyet, G.; Vladimirov, A. G.; 0000 0003 5341 0057 (Rachinskii, DI); Rachinskii, Dmitry I.We study the effect of noise on the dynamics of passively mode-locked semiconductor lasers both experimentally and theoretically. A method combining analytical and numerical approaches for estimation of pulse timing jitter is proposed. We investigate how the presence of dynamical features such as wavelength bistability in a quantum-dot laser affects timing jitter.
