Our work in this area can be separated into two categories: conceptual and experimental. Please read our publications linked below for more information.
- Fluxonic processing of photonic synapse events explores the use of simple SNSPD/JJ circuits that perform many functions associated with synaptic and dendritic computation in neural systems.
- Design of superconducting optoelectronic networks for neuromorphic computing was also presented at IEEE Rebooting Computing 2018. This work utilized the evolutionary optimization software developed by TennLabs in conjunction with a model of superconducting optoelectronic neurons to design networks capable of solving the TennLabs benchmark problems.
- Superconducting Optoelectronic Circuits for Neuromorphic Computing is our first paper on the subject. It represents our early thinking.
- An ultrahigh impedance superconducting thermal switch for interfacing superconductors with semiconductors and optoelectronics demonstrates a superconducting voltage amplifier enabling a mV superconducting signal to drive a semiconductor diode at 1V to generate light. This component is central to the ability to achieve superconducting optoelectronic neurons. The manuscript has been accepted for publication in Nature Electronics.
- Design, fabrication and metrology of 10x100 multi-planar integrated photonic routing manifolds for neural networks is a recent implementation of a feed-forward routing architecture with all-to-all connectivity using two photonic planes.
- Multi-planar amorphous silicon photonics with compact interplanar couplers, cross talk mitigation, and low crossing loss is our first demonstration of multi-planar waveguide interconnects. We show three planes of amorphous silicon waveguides with low-loss inter-planar couplers and crossings.
- Room-temperature-deposited dielectrics and superconductors for integrated photonics presents related integrated photonic demonstrations from our group at NIST.
We currently have opportunities for postdocs. NIST Boulder and the University of Colorado are within walking distance of each other, creating a vibrant intellectual and scientific community. With over 300 sunny days per year and ample opportunities for outdoor and cultural recreation, Boulder is an excellent place to live. The salary of a starting postdoc at NIST is $70,000, far superior to many academic postdoc salaries. Please contact Jeff Shainline (firstname.lastname@example.org) if you are interested in these opportunities.
