研究目的
Investigating the use of hybrid-cavity semiconductor lasers composed of a Fabry-Pérot (FP) cavity and a microcavity for realizing single mode operation and optical signal processing.

Hybrid-cavity semiconductor lasers with a square/rhombus microcavity connected with a FP cavity have been demonstrated for realizing single mode semiconductor lasers with a wide tuning range. Furthermore, all-optical switching of hybrid-cavity laser with a square microcavity is realized using optical trigger pulses at wavelengths around lasing and long wavelength non-lasing mode as set/reset signals.
