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 , Adam McCaughan and Jeff Shainline

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.

Thermally Coupled Imager for Performing Time and Position Sensitive Imaging of Single Photons

NIST Inventors

Adam McCaughan and Varun Verma

A SNSPD imager which will be capable of reading out at least tens of thousands of detectors. This array, the SNSPD "thermally-coupled imager" (TCI) efficiently multiplexes SNSPDs on a single readout line and is capable of resolving both location and time-of-arrival of single photons over a large {>

Diagram of the dual optical frequency comb spectrometer consisting of a single laser that is split into local oscillator, reference and probe legs to down-convert, interleave and normalize gas sample absorption signals.

Variable-Frequency Optical Combs, Heterodyne Sensor, and Process for Performing Spectroscopy

NIST Inventors

David F. Plusquellic , Kevin O Douglass and Adam J. Fleisher

This invention uses lasers and modulators to create special light waves called “optical frequency combs” that can scan multiple chemical features instantly. These combs detect chemicals by analyzing how light changes as it interacts with different substances. It’s fast, accurate, and doesn’t need
