Strongly enhanced local electromagnetic field in mid-infrared and terahertz photodetectors employing a hybrid antenna
A hybrid antenna consisting of a patch cavity and a metal grating is designed in this work. This antenna can effectively localize and enhance the intensity of the electric field inside a quantum well photodetector (QWP). The optical properties of the designed antenna are theoretically investigated,...
