摘要： An interband cascade (IC) optoelectronic device constructed to have a plurality of IC stages, wherein each of the IC stages comprises: a hole injector; an electron injector; an active region coupled to the hole injector and the electron injector and comprising a first layer, wherein the first layer comprises a first material, and wherein the first material comprises InAsP or AlInAsP; a conduction band running through the hole injector, the electron injector, and the active region; and a valence band running through the hole injector, the electron injector, and the active region. In certain embodiments, the IC optoelectronic device may be a laser (ICL), a light-emitting diode (LED), a superluminescent light-emitting diode (SLED), a photodector, or a photovoltaic device.
