Paper Abstract

We propose an active routing wavelength switch by applying Micro-Ring Resonators (MRR). In this paper, this device is designed that the optical signals can be switched by electric signals. The electric signals modulate free carrier concentration that can change the refractive index of MRR. We can control the condition of light coupling so that one can switch light way or one wish. Therefore, we utilize the Schottky diode that can be tuned the refractive index of MRR by dc voltage. With combining MRR artfully, we can design a novel n x n switch active device based on switch architecture. Firstly, we build a 2 x 2 routing wavelength switch by MRR. Then, we use the frame of 2 x 2 routing wavelength switch to develop the 4 x 4 routing wavelength switch. The 30μm×75μm 4×4 silicon-on-insulator (SOI) wavelength switch can switch 4 wavelengths following ITU grid. With launching light from different inputs and see the output channels, the output power were simulated by Finite Difference Time Domain (FDTD) method. The simulation results illustrates the feasibility to achieve full function of optical cross connect routing wavelength switch.
