Maximizing the performance for microcomb based microwave photonic transversal signal processors
Yang Sun, Jiayang Wu, Yang Li +8
Microwave photonic (MWP) transversal signal processors offer a compelling solution for realizing versatile high-speed information processing by combining the advantages of reconfig…
Optical Adaptive LMS Equalizer with an Opto-electronic Feedback Loop
Xumeng Liu, Xingyuan Xu, Arthur James Lowery
We propose a photonic adaptive Least-Mean-Squares equalizer with an opto-electronic feedback loop to determine the updating of an optical Finite-Impulse-Response filter's weights,…
Photonic single perceptron at Giga-OP/s speeds with Kerr microcombs for scalable optical neural networks
Mengxi Tan, Xingyuan Xu, David J. Moss
Optical artificial neural networks (ONNs) have significant potential for ultra-high computing speed and energy efficiency. We report a novel approach to ONNs that uses integrated K…
Microwave and RF signal processing based on integrated soliton crystal optical microcombs
Xingyuan Xu, Mengxi Tan, Jiayang Wu +3
Microcombs are powerful tools as sources of multiple wavelength channels for photonic RF signal processing. They offer a compact device footprint, large numbers of wavelengths, and…
Photonic single sideband RF generator based on an integrated optical micro-ring resonator
Xingyuan Xu, Jiayang Wu, Mengxi Tan +6
We demonstrate narrowband orthogonally polarized optical RF single sideband generation as well as dual-channel equalization based on an integrated dual-polarization-mode high-Q mic…
