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 1):
A semiconductor laser comprising:\n a substrate having a principal surface; a mesa structure disposed on the principal surface of the 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 a top surface, a bottom surface, a first side surface, a second side surface, and a third side surface; an emitter region including a first-conductivity-type semiconductor on at least one of the first side surface, the second side surface, the top surface, and the bottom surface of the active region; and a collector region including a quantum filter structure on at least one of the first side surface, the second side surface, and the third side surface of the active region, wherein the collector region is separated from the emitter region on the mesa structure, the first side surface and the second side surface extend in the direction of the waveguide axis, and the third side surface extends in a direction intersecting the waveguide axis.
