Abstract

The present canonical design of the semiconductor laser (SCL), in force since The early 1970s, is incompatible with high coherence (narrow linewidth). The reason is fundamental and is a consequence of the quantum-mandated umbilical relationship between induced emission (gain) and spontaneous emission (noise) exacerbated by the modal concentration of optical energy in the high loss III-V material. We demonstrate, theoretically and experimentally, a new design paradigm which results in over three orders of magnitude reduction in the spectral linewidth of the SCL compared to commercial lasers now deployed. The key difference is a radical (some 99% in our case) transfer of stored optical energy from the III-V material to nearly transparent silicon which is an integral part of the laser resonator. This laser should constitute a serious candidate to take over the role of the Distributed Feedback (DFB) SCL as the light source for future coherent optical networks.
