Abstract : The underlying principle of a photodetector is converting the optical signal into electrical signal. Under the radiation of an optical field, excess carriers are generated from the active region in the semiconductor, the electrons in conduction band and the holes in valence band. The increase of electron-hole pairs is bonding to the variation of the physical parameters. By analyzing the physical parameters through associated circuitry or systems, the characteristic of the incident photons can be identified. The use of plasmonic resonators for the enhancement of quantum dot photodetectors was also investigated.
