Abstract
In this paper, we propose and numerically investigate a novel method to generate optical frequency comb (OFC) based on mutual injection in a twin-stripe semiconductor laser (a cell array integrating two lasers on one chip in parallel). Because of the existence of optical confinement factors and the small waveguide spacing, considerable lateral coupling or mutual injection occurs between the two paralleling neighbors. The twin-stripe semiconductor laser will be driven into complex nonlinear dynamic states and can be employed to generate OFCs. The proposed mutual-injection-induced OFC generation method does not need any external microwave sources or modulators. Moreover, the compact OFC generator is free of any auxiliary optical passive devices required in the typical master-slave injection configuration. The numerical results show that the mutual-injection-induced OFC can be flexibly adjusted by changing the bias currents and the mutual injection parameters.
