We study the coupling and switching effects of two discrete relativistic quantum Jackiw-Rebbi states in interfaced binary waveguide arrays with cubic-quintic nonlinearity. Like in the case with Kerr nonlinearity, two Jackiw-Rebbi states can couple efficie... see more

We investigate the edge e?ects of the optical analogue of the quantum relativistic Dirac solitons in binary waveguide arrays with Kerr nonlinearity when one tail of the Dirac soliton is truncated. We show that if the outermost waveguide of the binary wave... see more

In this paper we review our works in the field of nonlinear optics in waveguide arrays (WAs) and photonic nanowires. We first focus on the new equation governing light propagation in optical fibers with sub-wavelength cores which simultaneously takes into... see more

The Slotted Waveguide Antenna Array (SWAA) was introduced since the decade of 40s.This type of antenna array is well known by its reliability and ability to handle large amounts of powerand high operating frequencies, so that the SWAA is commonly used as ... see more

In this work, new construction methods for self-dual codes are given. The methods use the short Kharaghani array and a variation of it. These are applicable to any commutative Frobenius ring. We apply the constructions over the ring F_2 + uF_2 and self-du... see more

By employing the complementary dipole antenna concept to the normal waveguide fed slot radiator, an improved antenna element with wide impedance bandwidth and symmetrical radiation patterns is developed. This is achieved by mounting two additional metalli... see more

Wavelength Division Multiplexing Passive Optical Network (WDM-PON) introduces high data rate and large bandwidth. A bidirectional WDM-PON system based on a Fabry-Perot laser diode (FP-LD) with two cascaded array waveguide gratings (AWGs) has been demnstra... see more

Here we propose a bidirectional wavelength division multiplexing (WDM) access architecture employing cascaded cyclic arrayed waveguide gratings (AWGs) and reflective semiconductor optical amplifiers (RSOAs) for system applications mainly in wavelength rou... see more

This paper introduces and discusses the study of a new concept for SIW array antenna development. This conducted development is based on three designs, two of them related to 1x2 arrays fed by SIW line, combined with SIW inset line, and the last designed ... see more
