The optical bound state in the continuum (BIC) is characterized by an extremely high-quality
factor resulting in a drastic enhancement of light-matter interaction phenomena. We study …

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 …

We investigate the formation of photonic bound states in the continuum (BICs) in photonic
crystal slabs from an analytical perspective. Unlike the stationary at-Γ BICs which originate …

We present a two-dimensional photonic crystal design of four defect dielectric rods, which
form a microcavity with eigenfrequencies residing in the propagating band of a directional …

We develop a semianalytical model to describe bound states in the continuum (BICs) in
photonic crystal slabs. We model leaky modes supported by photonic crystal slabs as a …

We use the real (Kerr) and imaginary (two photon absorption) parts of a third order optical
nonlinearity to tune the long (1.6 μ m) and short wavelength (1.3 μ m) band edges of a stop …

We analyze the resonant linear and nonlinear transmission through a photonic crystal
waveguide side-coupled to a Kerr-nonlinear photonic crystal resonator. First, we extend the …

The formation of tunable bound states in the continuum (BICs) within photonic crystal (PC)
slabs has been investigated by using a semianalytical coupled-wave theory framework. An …

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 …

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 …
