This paper studies the problem of data access at the receiver with large bit error rate and low
quality factor. Due to this issue the information got inaccurately at the receiver side, the data …

Photonic crystal based ring resonators are best choice for designing all-optical devices. In
this paper, we used a basic structure of photonic crystal ring resonators and designed all …

In this paper a novel all-optical logic AND, OR and XOR gates based on nonlinear
directional coupler theory is demonstrated. We use two waveguides for designing and …

Logic gates based on optical waveguides have been implemented in recent years. But the
use of the plasmonic effect on logical devices like semiconductor has not yet been …

A compact 3× 3 polydiacetylene crystalline multimode interference (MMI) coupler simulated
using the nonlinear modal propagation method (NMPA) is proposed as a conventional …
