An automatic laser power control scheme for the transistor laser has been developed and demonstrated using the transistor laser collector current output. The collector current enables an all-electrical feedback solution for laser power control, obviating the need for a hybrid integrated monitor photodiode. This control scheme enables the simple monolithic integration of the transistor laser and its power control circuits on a single die.
