Paper Abstract

We demonstrate fast power and wavelength control of a monolithic sampled grating distributed Bragg reflector (SGDBR) laser integrated with semiconductor optical amplifier (SOA). Optical power leveling for different channels can be achieved by tuning SOA driving current. Wavelength switching transients are analyzed experimentally. An appropriate shuttering operation of SOA sections during the channel switching process is implemented to eliminate the impact of transient emitting modes, and greatly improved dynamic performance of the SGDBR laser can be observed. With our design, output power of the laser can be precisely controlled within 0.1 dB and rapidly shuttered within 2 ns.
