CW and comb regimes in III-V SiN hybrid lasers with frequency-selective narrow band mirror

Abstract

We investigate the stability of III-V SiN hybrid lasers. By detuning the lasing frequency with respect to the narrowband mirror reflectivity peak, we observe regimes of ultra-damped relaxation oscillations, turbulence, and combs, caused by the interplay of four-wave mixing, Henry alpha-parameter and the narrowband reflectivity.
