All optical NAND gate based on nonlinear photonic crystal ring resonator

All optical 1 to 2 decoder based on photonic crystal ring resonator

In this paper we combined an optical mixer via photonic crystal ringresonator to propose an all optical 1 to 2 decoder. The main idea used in this paper isbased on controlling the optical behavior of the resonant ring via optical powerintensity. We know that resonant wavelength of the photonic crystal ring resonator isvery sensitive upon the refractive index of dielectric rods, on the other had...

Analysis of Protein Concentration Based on Photonic Crystal Ring Resonator

In this paper, homogeneous, wavelength shift biosensor is designed for sensing the protein concentration using two dimensional Photonic Crystal Ring Resonator (PCRR). The sensor is designed to monitor the protein concentration from 0% to 100%. The proposed sensor is composed of periodic Si rods embedded in an air host with a circular PCRR that is placed between the inline quasi waveguides. It i...

Ultra-Fast All-Optical Half Subtractor Based on Photonic Crystal Ring Resonators

Abstract: In this paper, we aim to design and propose a novel structure for all-opticalhalf subtractor based on the photonic crystal. The structure includes two optical switches,one power splitter, and one power combiner. The optical switches are made of theresonant rings which use the nonlinear rods for dropping operation. The footprint of thedesigned structure is about...

Optical NOR Logic Gate Based on Dual Circular Photonic Crystal Ring Resonator

We introduce a new configuration of optical NOR logic gateimplementedby using two symmetric circular shaped photonic crystal ring resonator made of dielectric Indium Phosphide rods in air substrate. The switching behavior of proposed optical gate was analyzed based on beam interference principle and perturbation theory. Numerical calculations were carried out by optiFDTD tool using a 2D FDTD do...
