Abstract
Thin-film Black Phosphorus (BP) has shown considerable promise as a material for mid-wave infrared photodetection. BP exhibits attractive materials properties that include a high photoresponse in the mid-wave infrared and an electrically tunable bandgap. However, bandgap tunability requires the material to be kept sufficiently thin, which limits the thickness, and therefore absorption, of a BP active layer in a photodetector. We have designed and characterized metamaterial gratings that increase the absorption in BP. We show that the metamaterial grating, when integrated into a photodetector, increases the photodetection capabilities of thin-film BP.
