Effect of nonlinear gain on the phase noise of Y-branch lasers: Numerical study

摘要

Effect of nonlinear gain on the phase noise of Y-branch lasers is studied by numerical simulations, which are based on the developed transmission line model (TLM) and multimode rate equations superposed by Langevin noise sources and nonlinear gain terms. The nonlinear gain is found to have severe effects on the phase noise of the Y-branch lasers.
