Tuning ofPhotonic Crystal Ring Resonators for Application in Analog to Digital Converter Systems
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2013, Vol 5, Issue 3
Abstract
In this paper we have proposed a tunable two dimensional (2D) photonic crystal (PhC) ring resonator configuration for application in optical analog to digital converter (ADC) systems. Quality factor and dropping efficiency at the resonance of our designed ring resonator are 202 and 100%, respectively. The quantity of transmission efficiency and quality factor (Q) are suitable for ADC applications. In this device the quality factor is considerably improved with respect to other published reports. We study parameters which have an effect on resonant wavelength in this ring resonator, such as dielectric constant of coupling, innerand whole rods of the structure. The area of the proposed structure is about 103?m2. Simulations are performed using 2D finite difference time domain (FDTD) method.
