We report on a path-independent insertion-loss (PILOSS) 8× 8 matrix switch based on Si-
wire waveguides, which has a record-small footprint of 3.5× 2.4 mm^ 2. The PILOSS switch
consists of 64 thermooptic Mach-Zehnder (MZ) switches and 49 low-crosstalk intersections.
Each of the MZ switches and intersections employs directional couplers, which enable the
composition of a low loss PILOSS switch. We demonstrate successful switching of digital-
coherent 43-Gbps QPSK signal.
