Abstract
The present disclosure relates to semiconductor structures and, more particularly, to optical neuro-mimetic devices and methods of manufacture. The structure includes: a plurality of photodetectors and electrical circuitry that converts photocurrent generated from the photodetectors into electrical current and then sums up the electrical current to mimic neural functionality.
Claims17
A structure comprising a plurality of photodetectors and electrical circuitry that converts photocurrent generated from the photodetectors into electrical current and then sums up the electrical current to mimic neural functionality;
- and
- a waveguide structure,
- wherein the plurality of photodetectors are arranged along a length of the waveguide structure and the each of the plurality of photodetectors are of a different length.
A structure comprising:
- a waveguide structure;
- a plurality of photodetectors coupled to the waveguide structure, each of which are capable of generating a photocurrent from light received as input from the waveguide structure;
- and
- electrical circuitry coupled to each respective photodetector of the plurality of photodetectors, the electrical circuitry converting the photocurrent into electrical current and then summing up the electrical current to provide a Sigmoid or Rectified Linear Unit (ReLU) neural transfer function,
- wherein the photodetectors are arranged along a length of the waveguide structure and each of the plurality of photodetectors are of a different length.
A method comprising;
- generating a photocurrent by a plurality of photodetectors;
- converting each photocurrent of the plurality of photodetectors into an electrical current;
- and
- summing up each electrical current converted from each photocurrent and outputting the sum of each electrical current as a Sigmoid or Rectified Linear Unit (ReLU) neural network function,
- wherein the photodetectors are arranged along a length of the waveguide structure and each of the plurality of photodetectors are of a different length.
