An all semiconductor swept laser source demonstrating continuous sweeping over a >11 nm range with a linewidth suitable for optical coherence tomography is proposed and demonstrated. The operation of this device relies upon state filling in a multiple contact laser utilizing quantum dots with strongly overlapping ground and excited states.
