We demonstrate an unconventional near infrared photodetector fabricated from a ZnO chip with a metallic subwavelength grating structure as contact and optical window, which harvests hot electrons generated by plasmonic resonances introduced by incident light. The grating structure has a strong selection of the polarization of incident light, meaning that the detector is naturally polarization-sensitive. In our device, the polarization extinction ratio is as high as 64:1, much higher than that relying on crystal orientations. Since the photoresponse is introduced by plasmonic resonance, a narrow photoresponse spectrum with a linewidth of 32.1 nm at 1.201 µm is obtained. By simply changing the grating period, the spectral position can be tail...
