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 …

Abstract 2D layered materials (2DLMs) are a subject of intense research for a wide variety of
applications (eg, electronics, photonics, and optoelectronics) due to their unique physical …

Integrated Kerr micro-combs are a powerful source of multiple wavelength channels for
photonic radio frequency (RF) and microwave signal processing, particularly for transversal …

We review recent work on broadband RF channelizers based on integrated optical
frequency Kerr micro-combs combined with passive micro-ring resonator filters, with …

The microscopic valence electron density determines the optical, electronic, structural and
thermal properties of materials. However, current techniques for measuring this electron …

We demonstrate enhanced four-wave mixing (FWM) in doped silica waveguides integrated
with graphene oxide (GO) layers. Owing to strong mode overlap between the integrated …

The present status and development of strong-field nano-optics, an emerging field of
nonlinear optics, is discussed. A nonperturbative regime of light-matter interactions is …

The translational symmetry breaking of a crystal at its surface may form two-dimensional
(2D) electronic states. We observed one-dimensional nonlinear optical edge states of a …

New results about relaxation dynamics of optically excited electrons in metals, mostly gold
and nickel films, are presented. Emphasis is on electron temperature near the surface as …
