Phase-encoded RF signal generation based on an integrated 49GHz micro-comb optical source
Xingyuan Xu, Mengxi Tan, Jiayang Wu +8
We demonstrate photonic RF phase encoding based on an integrated micro-comb source. By assembling single-cycle Gaussian pulse replicas using a transversal filtering structure, phas…
Microwave photonic fractional Hilbert transformer with an integrated optical soliton crystal micro-comb
Mengxi Tan, Xingyuan Xu, Bill Corcoran +8
We report a photonic microwave and RF fractional Hilbert transformer based on an integrated Kerr micro-comb source. The micro-comb source has a free spectral range (FSR) of 50GHz,…
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…
Microwave Q-band oscillator at 49GHz for broadband frequency conversion based on a Kerr optical soliton crystal micro-comb
Xingyuan Xu, Jiayang Wu, Mengxi Tan +6
We report a broadband microwave frequency converter based on a coherent Kerr optical micro-comb generated by an integrated micro-ring resonator. The coherent micro-comb displays fe…
Microwave photonic filters via radio frequency bandwidth scaling based on soliton crystal optical micro-combs
Xingyuan Xu, Mengxi Tan, Jiayang Wu +6
We demonstrate high-resolution photonic RF filters using an RF bandwidth scaling approach based on integrated Kerr optical micro-combs. By employing both an active nonlinear micro-…
