We experimentally study the nonlinear scattering by local photonic structures embedded in
continuous Kerr media and demonstrate nonlinear trapping in guiding structures and …

The transmission characteristics of simple nonlinear barriers are studied as functions of the
nonlinearity of the barrier media. Two different types of nonlinear systems are considered …

We employ an effective discrete model for the study of wave propagation in a photonic
crystal waveguide side-coupled to a cavity with Kerr-type nonlinearity. Taking into account …

A Fabry–Pérot cavity can be closed by reflecting slabs made with different types of materials.
An interesting situation occurs when the slabs are constructed from a photonic crystal in the …

A study is made of the exact solutions of a system of nonlinear difference equations that
model the propagation of electromagnetic radiation in photonic crystal waveguides and …

We show that two regimes of diffraction exist in arrays of waveguides, depending upon the
input conditions. At higher powers, normal diffraction leads to self-focusing and to the …

The nonlinear optical effects induced by a one-dimensional (1D) line defect, made of Kerr
material, in a 2D photonic crystal are studied. Comprehensive ab initio numerical …

We show that two nonlinear resonant cavities aligned between two parallel waveguides can
support self-induced bound states in the continuum (BSCs). These BSCs are symmetrical …

The reflectivity of a single-channel waveguide mode upon resonantly coupling to a Kerr-
active nonlinear resonant cavity is calculated analytically, including the effects of two-photon …

The propagation of waves in complex media can be harnessed either by taming the incident
wave-field impinging on the medium or by forcing waves along desired paths through its …
