This paper demonstrates the measurements of direct modulation bandwidth of a bistable racetrack semiconductor ring laser. It is exhibited using the phenomenon of optical injection-locking in the master-slave layout. Semiconductor ring laser is employed as the slave laser. Modulated signal is injected at 1530 nm, which is about 20nm away from the main lasing mode. The frequency response of the main...
The frequency response and alpha factor of monolithic semiconductor ring lasers (SRLs) with 150 micron radius are measured using an all-optical modulation technique, yielding a -3 dB, frequency of 11 GHz and alpha factor of 2.4.
