摘要
A high operating temperature split-off band infrared (SPIP) detector having a double and/or graded barrier on either side of the emitter is provided. The photodetector may include a first and second barrier and an emitter disposed between the first and second barriers so as to form a heterojunction at each interface between the emitter and the first and second barriers, respectively. The emitter may be of a first semiconductor material having a split-off response to optical signals, while one of the first or the second barriers may include a double barrier having a light-hole energy band level that is aligned with the split-off band energy level of the emitter. In addition, the remaining barrier may be graded.
