Inventors include Dr Chakresh Kumar; Dr Ghanendra Kumar; and Mr. Anuj Kumar.
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: A photodetector (100) is disclosed. The photodetector (100) comprises a substrate (102), an absorption layer (104) disposed over the substrate (102), and configured to absorb optical radiation (110) at a predefined telecommunication wavelength so as to generate a plurality of photogenerated carriers, a dielectric spacer layer (106) disposed over the absorption layer (104), a plurality of metallic nanoantennas (112) arranged in a periodic array and disposed over the dielectric spacer layer (106), and configured to generate a localized surface plasmon resonance (LSPR) that couples an electromagnetic field, through the dielectric spacer layer (106), into the absorption layer (104) so as to increase a rate of generation of the plurality of photogenerated carriers, a plurality of electrical contacts (108) coupled to the absorption layer (104), and configured to extract the plurality of ph
