Title:
Quantum cascade laser
Document Type and Number:
Japanese Patent JP5941655
Kind Code:
B2
Abstract:
A quantum cascade laser 1 includes a semiconductor substrate, an active layer 15 that is disposed on the semiconductor substrate and has a cascade structure in which a unit layered structure 16 including a quantum well light emitting layer and an injection layer is stacked in multiples to alternately stack the quantum well light emitting layer and the injection layer, and a diffraction grating layer 20 disposed on the active layer.
