Diagram showing the circuit for resetting the Spectral Power Distribution (SPD) after the Light Emitting Diode (LED) has emitted a photonic pulse.

Superconducting Opto-Electronic Transmitter Circuit

NIST Inventors

Sonia Buckley and Adam McCaughan

This invention describes a family of circuits that receive an input current or voltage pulse when a superconducting element has been driven above threshold, producing an amplified current or voltage pulse to drive a light source, and reset to the resting state after light has been generated.

A Better Way to Connect Fiber Optics to Computer Chips

NIST Inventors

Saeed Khan

This invention provides a way to efficiently connect optical fibers to semiconductor chips. It improves the transfer of light signals between the fiber and the chip, reducing loss and increasing performance. The design allows for better alignment and integration, making it easier to manufacture and

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
