Silica-based Low Loss And High Extinction Ratio 8x8 Thermo-optic Matrix Switch With Path-independent Loss Arrangement Using Double Mach-zehnder Interferometer Switching Units

摘要

We describe a low loss and high-extinction ratio 8 x 8 thermo-optic matrix switch with a reduced 8 stage configuration composed of silica-based planar lightwave circuits. The average insertion loss and the extinction ratio were 5.1 dB and 60.3 dB, respectively.
