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…
High third-order Kerr optical nonlinearity in BiOBr 2D films measured by the Z-scan method
Linnan Jia, Dandan Cui, Jiayang Wu +8
We investigate the nonlinear optical properties of BiOBr nanoflakes, a novel two-dimensional (2D) layered material from the Bismuth oxyhalide family. We measure the nonlinear absor…
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…
Integrated polarizers based on graphene oxide in waveguides and ring resonators
Jiayang Wu, Yunyi Yang, Yang Qu +7
Integrated waveguide polarizers and polarization-selective micro-ring resonators (MRRs) incorporated with graphene oxide (GO) films are experimentally demonstrated. CMOS-compatible…
Laser Cavity-Soliton Micro-Combs
Hualong Bao, Andrew Cooper, Maxwell Rowley +10
The field of micro-cavity based frequency combs, or 'micro-combs'[1,2], has recently witnessed many fundamental breakthroughs[3-19] enabled by the discovery of temporal cavity-soli…
