Photoresponse enhancement in nanoscale Ge photodetector through split bull's eye shaped plasmonic antenna
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.
