ABSTRACT
We have measured the enhancement in the response of a quantum well infrared detector by the incorporation of a metallic diffraction grating into the structure. We find an enhancement ratio of about 30, and its spectrum indicates that waveguiding of diffracted light occurs within the sample. Strong coupling to evanescent modes of the grating is not observed.
