| titleOfInvention | Absorption structure of infrared quantum well photoelectric detector |
| abstract | The invention, which belongs to the field of the optical device in sub-wavelength photonics, discloses an absorption structure of an infrared quantum well photoelectric detector. The absorption structure for coupling incident electromagnetic waves to a quantum well active region comprises an upper metal layer, an intermediate semiconductor layer, and a lower metal layer. The upper metal layer is a periodic metal square array, the intermediate semiconductor layer is a quantum well layer, and the lower metal layer is a flat metal plate having a surface with the periodic metal square array. According to the absorption structure, on the basis of coupling of a micro-cavity mode excited by a metal microstructure and a hybridized SSPs mode, absorption of infrared radiation by the quantum well active region can be improved obviously and the electric field component (Ez) that is vital to quantum well absorption and is perpendicular to the quantum well plane is effectively enhanced, thereby overcoming a defect that the traditional quantum well infrared photoelectric detector does not absorb incident infrared radiation. With the structure, the detection efficiency of the ultra-far infrared photoelectric detector can be improved obviously. |
