ABSTRACT:
The present invention provides semiconductor lasers having an Active-Photonic-Crystal (APC) structure that allows scaling of the coherent power by using a waveguide having a periodic structure that selects operation in a single spatial mode from large-aperture devices. The lasers include an active medium that includes an array of quantum box ministacks, each ministack containing 2 to 5 vertically stacked, coupled quantum boxes.
