Abstract

A hybrid integrated tunable narrow-linewidth laser is demonstrated in this paper. The hybrid laser comprises a commercial DFB laser butt-coupled to an external cavity with a micro-ring resonator. A transfer matrix model has been presented and the wavelength performance of the laser has been analyzed. In the experiment, the hybrid laser Lorentzian linewidth is ~5KHz and the tuning range is ~2.75 nanometer.
