Design and analysis of resonant cavity enhanced photodetector by using InP-based concentric circular subwavelength grating

This paper presents the design and analysis of a novel resonant cavity enhanced photodetector which is realized by utilizing concentric circular subwavelength gratings (CC-SWGs) as reflective mirrors. The CC-SWG proposed here can achieve a reflectivity of higher than 99% within a broad wavelength range from 1.37 to 1.63 µm. The calculated peak quantum efficiency of the designed photodetector can achieve 90% at 1.55 µm.
