A layered metastructure (LM) formed by a quasi‐periodic arrangement of graphene and
isotropic dielectric mediums, which can realize the functions of the tunable logic gate and …

TOAD or Tera Hertz Optical Asymmetric Demultiplexer is an optical switch. Using this switch,
we have invented an optical comparator. This optical comparator circuit is very simple in …

Photonic band gap (PBG) crystal is the platform for the localization of the light beam, which
provides a gateway for doing the different types of logic operations by applying some …

Recently, photonic crystals have paved the way to control photonic signals. Therefore, this
research numerically investigated the design of the optical switch using the guided-mode …

We develop an all-optical two-state Pauli X logic gate, using two-dimensional nano-photonic
crystals (PhCs) based on photonic-crystal semiconductor optical amplifier switches (pc …

Abstract The use of a newly designed silicon dumbbell-shaped micro-ring resonator-based
device was conceptualised for sensing applications. In particular, an illustrative example of …

In this paper, we propose a hybrid amplifier-based 8-port Cross-Polarization Modulation
(XPoM) interconnection with low polarization sensitivity unlike conventional Semiconductor …

In this paper, the simulation and analysis of the all-optical NOT logic gate using photonic
crystal semiconductor optical amplifier (PC-SOA) based on Mach-Zehnder interferometer …
