Abstract
We investigate a resonant photodiode transferred onto a gold mirror. This comprises a backside dielectric subwavelength periodic structure and an absorbing region as thin as 90 nm. Electro-optical characterizations of individual pixels featuring focal-plane array-compatible geometries are fully explained by electro-magnetic simulations. In particular, we observe a near perfect collection of the photo-carriers and external quantum efficiency of up to 71% around 1.55 μm.
