  • Patent number: 9806217
    Abstract: A metal-semiconductor-metal photodetecting device and method of manufacturing a metal-semiconductor-metal photodetecting device that includes a p-type silicon substrate with an oxide layer disposed on the p-type silicon substrate. Schotty junctions are disposed adjacent to the oxide layer on the p-type silicon substrate and a plasmonic grating disposed on the oxide layer. The plasmonic grating provides wavelength range selectability for the photodetecting device.
