A Metal-Insulator-Metal (MIM) plasmonic optical microcavity is proposed to be integrated with an InP based single photon avalanche diode (SPAD). The MIM microcavity includes a large top metallic grating to couple incident light into the cavity and a small bottom metallic grating to couple the light into the APD, which provides a possibility to improve the SPAD's performance through decreasing the...
A Metal-Insulator-Metal (MIM) Plasmonic Focusing Cavity is simulated. The structure includes a large upper metallic grating to couple incident light into the cavity and a small lower metallic grating to couple the light into the Avalanche Photodiode (APD) below the MIM cavity. Our results provide a possibility to reduce the dark current of an InGaAs/InP APD operated under the Geiger mode through decreasing...
Infrared light emitting diodes efficiency based on GaAs substrate has been limited due to light trapping and total internal reflection of GaAs materials. In this paper we introduced a new method of combining surface plasmonic effect and photonic crystal structure to enhance not only light extraction efficiency but also internal quantum efficiency. Through Finite Difference Time Domain method we found...
