Abstract
A method and apparatus for calibrating and controlling tunable lasers are disclosed. Multiple methodologies disclosed herein may be used, alone or in combination, which significantly speed up a calibration time and thus provide a significant advantage over existing technology in calibrating the tunable lasers. Certain methodologies benefit from a unique design of the tunable lasers that couple two or more optical facets to an output. The tunable lasers may be equipped with two or more sampled grating distributed Bragg reflector (SGDBR) mirrors and may include Semiconductor Optical Amplifiers (SOAs) after the SGDBR mirrors.
