Laser Dynamics Providing Enhanced-Modulation Bandwidth

摘要

In the last decades, various solutions have been proposed to increase the modulation bandwidth and consequently the transmission bit rate of integrated semiconductor lasers. In this manuscript we review some of them, trying to analyze for each one the mechanisms producing the modulation bandwidth extension. A comparison of the various approaches used for in-plane lasers is presented, in terms of both small and large signal modulation responses calculated using a Finite Difference Time Domain (FDTD) numerical simulator.
