Microresonator-enhanced, Waveguide-coupled Emission from Silicon Defect Centers for Superconducting Optoelectronic Networks
A. N. Tait, S. M. Buckley, A. N. McCaughan +4
Superconducting optoelectronic networks could achieve scales unmatched in hardware-based neuromorphic computing. After summarizing recent progress in this area, we report new resul…
Optimization of photoluminescence from W centers in silicon-on-insulator
Sonia M. Buckley, Alex N. Tait, Galan Moody +7
W centers are trigonal defects generated by self-ion implantation in silicon that exhibit photoluminescence at 1.218 m. We have shown previously that they can be used in wavegui…
Programmable Silicon Photonic Optical Thresholder
Chaoran Huang, Thomas Ferreira de Lima, Aashu Jha +4
We experimentally demonstrate an all-optical programmable thresholder on a silicon photonic circuit. By exploiting the nonlinearities in a resonator-enhanced Mach-Zehnder interfero…
Noise Analysis of Photonic Modulator Neurons
Thomas Ferreira de Lima, Alexander N. Tait, Hooman Saeidi +5
Neuromorphic photonics relies on efficiently emulating analog neural networks at high speeds. Prior work showed that transducing signals from the optical to the electrical domain a…
Digital Electronics and Analog Photonics for Convolutional Neural Networks (DEAP-CNNs)
Viraj Bangari, Bicky A. Marquez, Heidi B. Miller +6
Convolutional Neural Networks (CNNs) are powerful and highly ubiquitous tools for extracting features from large datasets for applications such as computer vision and natural langu…
ITO-based Electro-absorption Modulator for Photonic Neural Activation Function

An ultrahigh-impedance superconducting thermal switch for interfacing superconductors to semiconductors and optoelectronics
A. N. McCaughan, V. B. Verma, S. Buckley +5
A number of current approaches to quantum and neuromorphic computing use superconductors as the basis of their platform or as a measurement component, and will need to operate at c…
Demonstration of multivariate photonics: blind dimensionality reduction with analog integrated photonics
Alexander N. Tait, Philip Y. Ma, Thomas Ferreira de Lima +5
Multi-antenna radio front-ends generate a multi-dimensional flood of information, most of which is partially redundant. Redundancy is eliminated by dimensionality reduction, but co…
