Design Of Clocked Jk Flip Flop Using Air Hole Structured Photonic Crystal

Abstract

In this paper an advanced air-hole type photonic crystal is used to design a clocked JK flip flop. A uniform GaAs photonic crystal that has the refractive index of 2.95 with air hole structure is utilized. Photonic crystal is created with multi-mode interference (MMI) for three input ports which represent three inputs Clock, J and K. The given structure is resulted with 8.657 contrast ratio and the power output is 6.24dB. The response time of the structure is less than 0.27 ps. The overall design and the results are discussed through the experimental implementation and the numerically simulation to confirm its operation and feasibility. The response time of the structure is very less. The simplicity of the crystal, contrast ratio, power output and quick response time makes more suitable to be a part of optical integrated circuits.
