Abstract
A high-extinction ratio and low-loss silica-based 8 x 8 thermooptic ma trix switch is demonstrated. The 8 x 8 matrix switch is realized by us ing a double Mach-Zehnder interferometer switching unit and a matrix a rrangement which reduces the total waveguide length. The average extin ction ratio and the average insertion loss are 60.3 and 5.2 dB, respec tively.
