Fabrication methods for integrating 2D materials
David Moss
With compact footprint, low energy consumption, high scalability, and mass producibility, chip-scale integrated devices are an indispensable part of modern technological change and…
Integral order photonic RF and microwave signal processors based on soliton crystal Kerr micro-combs
Mengxi Tan, Xingyuan Xu, David J. Moss
Soliton crystal micro-combs are powerful tools as sources of multiple wavelength channels for radio frequency (RF) signal processing. They offer a compact device footprint, large n…
Highly tunable broadband RF photonic fractional Hilbert transformer based on a Kerr soliton crystal microcomb source
Mengxi Tan, Xingyuan Xu, David J. Moss
We demonstrate an RF photonic fractional Hilbert transformer based on an integrated Kerr micro-comb source featuring a record low free spectral range of 48.9 GHz, yielding 75 micro…
High bandwidth temporal RF photonic signal processing with Kerr micro-combs: integration, fractional differentiation and Hilbert transforms
Mengxi Tan, Xingyuan Xu, Jiayang Wu +1
Integrated Kerr micro-combs, a powerful source of many wavelengths for photonic RF and microwave signal processing, are particularly useful for transversal filter systems. They hav…
Broadband photonic RF channelizer with a Kerr soliton crystal micro-comb
Mengxi Tan, Xingyuan Xu, David J. Moss
We report a 92 channel RF channelizer based on a 48.9 GHz integrated micro-comb that operates via soliton crystals, together with a passive high-Q ring resonator that acts as a per…
Reconfigurable photonic RF filters based on integrated Kerr frequency comb sources
Xingyuan Xu, Mengxi Tan, Jiayang Wu +6
We demonstrate two categories of photonic radio frequency (RF) filters based on integrated optical micro-combs. The first one is based on the transversal filtering structure and th…
