Abstract:

A canonical semiconductor laser has photons both generated and stored in the same, optically lossy, III-V material. This leads to an excessive and large amount of noisy spontaneous emission commingling with the laser mode, thereby degrading its coherence. Here, we propose a new design paradigm for the semiconductor laser, where by the incorporation of a very high Q resonator as an integral part of the laser cavity, we demonstrate a semiconductor laser with a spectral linewidth of 18 kHz in the telecom band around 155 micrometers.
