Abstract

We present a novel design of a two-layer Mach-Zehnder Interference switch using silicon-on-insulator integrated optical technology. According to the design, we can reduce the size of Mach-Zehnder Interference switches with six refractive index adjustment cases by Beam Propagation Method (BPM) simulation. Some cases of better switches are sorted by tuning the phase difference between the two paths of the Mach-Zehnder Interference refractive indexes of the rib bending waveguide. Such a device shows great potential in achieving coarse wavelength division routing devices.
