Optical Frequency Combs in External Cavity SiN Hybrid Lasers
We analyze the emergence of optical frequency combs in a III-V SiN hybrid laser. Our model accounts for the narrow band effective mirror reflectivity and allows to simulate laser dynamics as a function of the bias current and the detuning of the lasing frequency with respect to the effective reflect...

| description | We analyze the emergence of optical frequency combs in a III-V SiN hybrid laser. Our model accounts for the narrow band effective mirror reflectivity and allows to simulate laser dynamics as a function of the bias current and the detuning of the lasing frequency with respect to the effective reflectivity peak. The physical mechanisms triggering multimode dynamics are analyzed in detail, with a focus on the generation of frequency combs, which are characterized in terms of bandwidth, line separation, phase and amplitude noise. |
