In this paper, we propose a novel sensor structure based on the rectangular ring resonator with the photonic crystal microcavity (PCM), and optimize the structure using finite-difference time-domain (FDTD) method. This sensor consists of the rectangular resonator with total internal reflection mirror and the PCM, which can be placed at the nearby optical waveguide of the rectangular ring resona...

We report experimental demonstration of fast light in an over-coupled ultra-compact silicon ring resonator with resonance-splitting. Strong mutual-coupling induced by the grating inside the ring leads to split resonances and accompanying large anomalous dispersion, thus providing a new approach to realizing fast light in the over-coupled region of the ring resonator. In the experiment, a maximu...

Abstract Micro Ring Resonator (MRR) is a successful micro-device with the help of which different types optical logic gates, processors, arithmetic units, etc. can be designed and integrated easily into modern high-speed communication network. In this article, at first, author has explained switching mechanism MRR then an optically controlled Feynman gate (i.e. reversible controlled-Not gate) u...

We propose and demonstrate a self-coupled micro-ring resonator for resonance splitting by mutual mode coupling of a cavity mode and a counter-propagating mode in a silicon-on-insulator platform. The resonator is constructed with a self-coupling region that can excite a counter-propagating mode. We experimentally study the effect of self-coupling on the resonance splitting, resonance extinction,...
