Abstract :
We report on a path-independent insertion-loss (PILOSS) 8 × 8 matrix-switch based on Si-wire waveguides, which has record-small footprint of 3.5 × 2.4 mm2. The matrix consists of thermooptic Mach-Zehnder switches and low-crosstalk intersections. Successful switching of 43-Gbps digital-coherent QPSK signal is demonstrated.
