Demonstration of Superconducting Optoelectronic Single-Photon Synapses

October 6, 2022
Author(s)
Saeed Khan, Bryce Primavera, Jeff Chiles, Adam McCaughan, Sonia Buckley, Alexander Tait, Adriana Lita, John Biesecker, Anna Fox, David Olaya, Richard Mirin, Sae Woo Nam, Jeff Shainline
Superconducting optoelectronic hardware is being explored as a path towards artificial spiking neural networks with unprecedented scales of complexity and computational ability. Such hardware combines integrated-photonic components for few-photon, light

Characterization of waveguide-integrated single-photon detectors using integratedphotonic structures

Sonia M. Buckley, Alexander N. Tait, Jeffrey T. Chiles, Adam N. McCaughan, Saeed Khan, Richard Mirin, Sae Woo Nam, Jeffrey M. Shainline
We show several techniques for using integrated-photonic waveguide structures to simultaneously characterize multiple waveguide-integrated superconducting-nanowire detectors with a single fiber input. We demonstrate structures for direct comparison of

Low-loss, high-bandwidth fiber-to-chip coupling using capped adiabatic tapered fibers

Saeed Khan, Jeff Shainline, Richard Mirin, Sae Woo Nam, Sonia Buckley, Jeff Chiles
We demonstrate adiabatically tapered fibers terminating in sub-micron tips that are clad with a higher-index material for coupling to an on-chip waveguide. This cladding enables coupling to a high-index waveguide without losing light to the buried oxide. A
