Design and Analysis of Ring Resonator Based Optical Delay Line

Abstract

Generation of optical delay line is one of the greatest challenges in the modern photonics. Optical delay lines are important functional elements in optical science and technology. In the areas of optical signal buffering, optical communication systems, phased arrays antenna and photonic signal processing optical delay line plays a very important role. In this paper, we are presenting a novel structure for optical delay line using ring resonator waveguide. A delay line device consists of three ring resonator waveguides and one bus waveguide. Transfer Matrix method is used to analyze the ring resonator which has been designed for single mode. From the designed delay modeling configuration we can achieve a delay of ~500ps.
