Fiber-To-Chip Coupler

NIST Inventors

Saeed Khan

A fiber-to-chip coupler includes a substrate, a waveguide on a top surface of the substrate, an optical fiber axially aligned to the waveguide, and a cap. The waveguide has a uniform region with uniform width and a tapered-waveguide region having a width that adiabatically increases from a minimum

Fluxonic Processor And Processing Photonic Synapse Events

A fluxonic processor includes processes photonic synapse events and includes a transmitter that receives neuron signal and produces output photons; a neuron that receives a dendrite signal and produces the neuron signal from the dendrite signal; a dendrite that receives a synapse signal, and

Josephson Junction Circuits For Single-Photon Optoelectronic Neurons And Synapses

NIST Inventors

Adam McCaughan and Manuel Castellanos Beltran

Single-photon optoelectronic neurons convert the optical signals of single photons to the electrical domain where summing and thresholding operations are performed. In these circuits, the photonic signals are converted to an electronic signal using a superconducting single-photon detector in

Neuromimetic Circuit

NIST Inventors

Sonia Buckley

Optoelectronic neural networks comprise a system of interconnected processing units (neurons) interconnected by integrated photonic waveguides. The processing units receive photonic signals from other units. Each unit sums the received signals on a waveguide-integrated photon detector, and when the
