In its 60 years of existence, the field of nonlinear optics has gained momentum especially
over the past two decades thanks to major breakthroughs in material science and …

The first nonlinear-optical experiments with graphene date back over a decade, and a wide
range of research breakthroughs has been reported since then, particularly on the third …

Resistive switching memory, which combines simple architectures with the ability of high
density, high switching speed, and low power consumption, has sparked a lot of attention in …

Perovskite photovoltaics have appeared as a promising technology for new-generation
photovoltaics. Developing a hole blocking layer (HBL) has also proven to be a successful …

We theoretically investigate ultrafast and nonlinear optical properties of graphite thin films
based on first-principles time-dependent density functional theory. We first calculate electron …

Recently, the nonlinear optical response of graphene has been widely investigated, as has
the integration of this 2D material onto dielectric waveguides so as to enhance the various …

We develop from first principles a theoretical model for infrared pulse propagation in
graphene-covered hybrid waveguides. We model electron dynamics in graphene by Bloch …

We study saturable absorption in graphene-comprising nanophotonic waveguides taking
into account the finite relaxation time as well as the carrier diffusion due to the nonuniform …

We study supercontinuum (SC) generation in graphene-covered nanowires based on a
generic model that correctly accounts for the evolution of the photon number under Kerr and …

We present the study of a proof-of-concept integrated device that can be used as a nonlinear
broadband isolator. The device is based on the asymmetric loading of a highly-confining …
