Design and Simulation of Ring Resonator Optical Switches using Electro-Optic Materials
نویسندگان
چکیده
Ring resonator optical switches using electro-optic materials have been proposed. The propagation loss of the waveguides and the resonance characteristics of ring resonators with different refractive indices are simulated. The operation voltage is estimated based on the results of the simulations and is found to be 0.70V in the case of the ring resonator switch with a K(Ta, Nb)O3 core and KH2PO4 cladding layers. The time-dependent resonance characteristics are calculated by a simple model. The operation speed is limited by the resonance time and is less than 15 ps. This is different from optical switches with a Si core, where their operation speed is limited by not the resonance time but the free carrier accumulation time of the order of 10 ps. Ring resonator switches with electro-optic materials are promising devices for application to optically interconnected LSIs because of their size of around 20 mm and high operation frequency of more than 66GHz.

Analytical Study of Optical Bi-Stability of a Single-Bus Resonator Based on InGaAs Micro-Ring Array
In this paper, for the first time to our knowledge, we investigate the optical bi-stability in a compact parallel array of micro- ring resonators with 5μm radius, induced by optical nonlinearity. Due to the nature of perfect light confinement, resonance and accumulation process in a ring resonator, optical nonlinear effects, even at small optical power of a few milliwatts in this structure are ...
