Abstract

Characterization of noise-induced phase synchronization (NIPS) in a vertical-cavity surface-emitting laser (VCSEL) is reported. An optimal amount of white, gaussian noise induces an effective phase entrainment between the polarized laser emission and the periodic pump modulation. The phenomenon is characterized through suitable indicators as the average frequency of the output signal and the diffusion coefficient of the relative phase. Their values are roughly independent on different waveforms of periodic input, provided that a simple condition for the amplitudes is satisfied. The experimental results are compared with a Langevin model, Monte-Carlo simulations and analytical solutions of a Master equation for the phase dynamics.
