Application of Au Rods metasurface in multiple quantum well infrared photodetectors
2021 4th International Conference on Electron Device and Mechanical Engineering (ICEDME)(2021)
摘要
We have realized the optical response of QWIPs to vertical incident infrared light by using a novel surface plasmon type metasurface optical coupling structure. The average transmittance of GaAs/AlGaAs QWIPs with Au Rods metasurface structure in the wavelength range of 7-9um is over 64%, the peak transmittance around 7.6um can reach 68%. In liquid nitrogen temperature and blackbody source conditio...
