Abstract：

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　conditions,　the　peak　response　of　the　device　is　8.5uV　and　peak　SNR　is　686.　©　2021　IEEE.
