From: Measurement of bound states in the continuum by a detector embedded in a photonic crystal
(a) SEM image of a cleaved PCS (left) and a schematic sketch of the device (right). The photonic crystal is processed into the active photodetector material. The photocurrent is collected via doped contact layers on the top and bottom of the suspended PCS membrane. (b) Measurement setup consisting of (left to right) the FTIR, an aperture, a polarizer, a lens and the measured PCS photodetector, mounted inside a liquid He cryostat.
