Photoresponse Enhancement in Nanoscale Ge Photodetector through Split Bull’s Eye Shaped Plasmonic Antenna

Not Accessible

Your library or personal account may give you access

Abstract

We exploit the idea of split bull’s eye antenna for a nanometer-scale germanium photodetector operating at a standard communication wavelength of 1310 nm. The nontraditional plasmonic metal aluminum has been implemented in the resonant antenna structure fabricated by standard CMOS processing. A significant enhancement in photoresponse is achieved in split bull’s eye scheme due to an increased optical near-field in the active region.
