Abstract

A 4 × 4 optical router which is composed of only four micro-ring resonator based switching elements is designed without any need of optoelectronic conversion for use in integrated optical networks. The geometrical structure including the number of rings and waveguide junctions are optimized through numerical simulation, which minimizes the crosstalk and the transmission loss and improves the loss of different paths of the optical router. The design can route four optical single-wavelength input signals to any of the four output ports and provided extinction ratio larger than 14 dB for all available optical paths. The average switching power consumption is about 1.2 mW per ring. The routing functionality and optical signal reliability are confirmed through numerical simulation.
