Abstract:
A semiconductor laser includes a mesa structure disposed on a principal surface of a substrate, the mesa structure extending in a direction of a waveguide axis, the mesa structure including an active region that includes a plurality of quantum well structures arranged in a direction of a first axis intersecting the waveguide axis, the active region having top and bottom surfaces, and first, second, and third side surfaces; an emitter region disposed on at least one of the first and second side surfaces, and the top and bottom surfaces; and a collector region including a quantum filter structure disposed on at least one of the first, second, and third side surfaces. The collector region is separated from the emitter region on the mesa structure. The first and second side surfaces extend in the direction of the waveguide axis. The third side surface extends in a direction intersecting the waveguide axis.

Claim (Index 7):
The semiconductor laser according to  claim 1 ,\n wherein the quantum filter structure includes a first III-V compound semiconductor layer containing three or more elements including aluminum as a group III constituent element and a second III-V compound semiconductor layer containing three or more elements including gallium as a group III constituent element.
