Abstract

Semiconductor passively mode-locked lasers (PMLLs) are receiving increasing attention as compact multicarrier sources for wavelength division multiplexed (WDM) optical interconnects for future data center networks [1]. Quantum well (QW) based MLLs, in particular, being mature from a manufacturing point of view and providing large output power over a relatively narrow bandwidth, are very attractive optical frequency comb generators for datacom applications. However, their large optical confinement factor may have a detrimental impact on the laser intensity and phase noise, thus limiting the communication system performance.
