The quest for all-optical signal processing is generally deemed to be impractical because
optical nonlinearities are usually weak. The emerging field of nonlinear photonic crystals …

This textbook offers the first unified treatment of wave propagation in electronic and
electromagnetic systems and introduces readers to the essentials of the transfer matrix …

Nonlinear materials can exhibit bistability, namely support different possible outputs for the
same input, depending on the excitation history. This property can find direct application to …

We study localized modes in uniform one-dimensional chains of tightly packed and
uniaxially compressed elastic beads in the presence of one or two light-mass impurities. For …

We present an overview of the properties of nonlinear guided waves and (bright and dark)
spatial optical solitons in a periodic medium created by linear and nonlinear waveguides …

Optical limiters are designed to transmit low-intensity light, while blocking the light with
excessively high intensity. A typical passive limiter absorbs excessive electromagnetic …

The nonlinear properties of quasi-periodic photonic crystals based on the Thue–Morse
sequence are investigated. The intrinsic spatial asymmetry of these one-dimensional …

We study the vibrational spectra of one-dimensional statically compressed granular crystals
(arrays of elastic particles in contact) containing light-mass defects. We focus on the …

Localized states in the constant-index and graded-index media separated by thin defect
layer (interface) are considered. Exact solutions to Schrödinger equation with the delta …

In this work, we study the defect mode and bistability behavior of 1-D photonic band gap
structure with magnetized plasma and coupled nonlinear defects. The transfer matrix …
