Plasmonic single-mode Fabry–Perot lasers based on Schottky contact

The single-mode plasmonic Fabry–Perot (FP) lasers are designed by introducing an inversely heavily doped semiconductor layer to the Schottky contact, to provide both carrier confinement and adjustable barrier for the III–V type high gain materials. The pixel method is also used to allocate non-periodic slot positions onto the FP cavity for the single-mode filtering and selection.
