Abstract

An 8×8 path-independent insertion-loss (PILOSS) switch based on Si-wire waveguides, which has a record-small footprint of 3.5×2.4 mm2, is reported. The PILOSS switch includes 64 thermooptic Mach-Zehnder switches and 49 low-crosstalk intersections. These switches and intersections utilize directional couplers, which make possible to compose a low loss PILOSS switch. The PILOSS switch exhibits successful switching of digital-coherent 43-Gbps QPSK signal.
