Abstract

We demonstrate hybrid integration of an RSOA with an extended-distributed Bragg reflector (E-DBR) laser cavity implemented on a Si3N4 chip with monolithically in-tegrated piezoactuators. The laser exhibits intrinsic linewidth of 4 Hz with laser frequency tuning over 1.0 GHz at up to 1 MHz triangular chirp rate.
