Abstract

To overcome the limited modulation bandwidth of directly modulated semiconductors, a novel scheme for modulation bandwidth enhancement and tailoring is presented. This scheme involves a single-frequency master laser monolithically integrated with strongly injection-locked whistle-geometry semiconductor ring lasers. Improved high-speed performance of the novel scheme is confirmed through numerical modeling, showing greatly enhanced resonance frequency of up to ~160 GHz. Approaches to further improve the modulation response of strongly injection-locked ring lasers, including cascaded injection-locking and Q-modulated injection-locking are also presented.
