Optical Crossbar Switch Using Fifth-order Resonators

摘要

A crossbar switch has been designed and fabricated using 0.075 mm~2-area, fifth order resonant switch elements. Multi-level-metal is implemented to allow addressing of high-density photonic elements and lead connections out to the photonic circuit boundary. A 2×2 crossbar switch is analyzed with four switch elements on a grid of orthogonal input and output bus waveguide. Path dependent power penalties of 0 dB to 1.5 dB for 10 Gb/s data and 20 dB to 36 dB crosstalk levels are measured for the four tested paths.
