Abstract
Intermodal oscillation of multimode InGaAs/InP lasers at X-Band frequencies are stabilized using self-forced oscillation of self-injection-locked, triple-phase-locked loop (SILTPLL), self-mode-locking (SML) and a combination of SML and SILTPLL. As the number of SML modes are increased, lower phase noise close to the carrier is measured. With 201 modes with intermodal oscillation frequency of 10 GHz, a phase noise of - 157 dBc/Hz at 10 kHz offset from a 10 GHz carrier is predicted, while any random phase error among self-mode-locked modes can be corrected using a self-forced oscillation technique. A compact realization is feasible using a heterogeneously integrated InP multimode laser (MML) on Si photonics, using low loss SiN resonators as delay elements and SiGe low noise RF electronics.
