Abstract

A hybrid laser with an optical negative feedback circuit integrated on a silicon photonics chip was investigated. Our numerical analysis verified that the laser can function as a wavelength-tunable laser with a spectral linewidth of less than 10 kHz. The result was supported by experiments.
