Paper Abstract

In this paper, we propose and demonstrate a novel generation scheme for the optical frequency comb (OFC), which is pumped by the optical injection and enhanced by the self-recirculating modulation. A directly modulated semiconductor laser under the optical injection is driven into the nonlinear period-one oscillation dynamic, which provides a primary OFC seed source with only several sparse comb lines and poor flatness. An enhanced OFC can be generated by modulating this directly modulated semiconductor laser in a closed loop, wherein the modulating signal is derived from the primary OFC. The performance of the proposed OFC is optimized through controlling the injection parameters and the self-recirculating modulation index.
