The present invention provides semiconductor lasers having an Active-Phot onic-Crystal (APC) structure that allows scaling of the coherent power by us ing a waveguide having a periodic structure that selects operation in a sing le spatial mode from large-aperture devices. The lasers include an active me dium that includes an array of quantum box ministacks, each ministack contai ning 2 to 5 vertically stacked, coupled quantum boxes.
