Graphene oxide (GO) was initially developed to emulate graphene, but it was soon
recognized as a functional material in its own right, addressing an application space that is …

Optical frequency combs offer an unrivalled degree of frequency measurement precision
that underpins the advance of modern technology in both fundamental science and …

Optical microcombs represent a new paradigm for generating laser frequency combs based
on compact chip-scale devices, which have underpinned many modern technological …

In many disciplines, states that emerge in open systems far from equilibrium are determined
by a few global parameters,. These states can often mimic thermodynamic equilibrium, a …

Convolutional neural networks, inspired by biological visual cortex systems, are a powerful
category of artificial neural networks that can extract the hierarchical features of raw data to …

As a fundamental optical approach to interferometry, Sagnac interference has been widely
used for reflection manipulation, precision measurements, and spectral engineering in …

Laser cavity-solitons can appear in a microresonator-filtered laser when judiciously
balancing the slow nonlinearities of the system. Under certain conditions, such optical states …

We report a photonic-based radio frequency (RF) arbitrary waveform generator (AWG) using
a soliton crystal micro-comb source with a free spectral range (FSR) of 48.9 GHz. The comb …

Micro-combs-optical frequency combs generated by integrated micro-cavity resonators–offer
the full potential of their bulk counterparts, but in an integrated footprint. They have enabled …

We review recent work on narrowband orthogonally polarized optical RF single sideband
generators as well as dual-channel equalization, both based on high-Q integrated ring …
