Photonic structures have been attracting more attention due to their ability capture, concentrate and propagate optical energy. In this work, we propose a photon-trapping hole-array structure integrated in nip InAsSb-GaSb heterostructure for the enhancement of photoresponse both near- mid-infrared regions. The proposed symmetrical hole array can increase photon lifetime inside absorption layer ...

In this paper, photodetection properties of a Graphene-based device at the third telecommunication window have been reported. The structure of the device is a Graphene-silicon Schottky junction which has been simulated in the form of an infrared photodetector. Graphene has specific electrical and optical properties which makes this material a good candidate for optoelectronic applications. Phot...

Proofs of the quantum advantage available in imaging or detecting objects under illumination can rely on optimal measurements without specifying what they are. We use continuous-variable Gaussian information formalism to show that is better for object detection compared with coherent states same mean photon number, even simple direct photodetection. The persists if signal energy and reflectivit...
