Using a compact (0.03 mm2) silicon-photonic bias-free thermo-optic cross-bar switch, we demonstrate microsecond-scale switching of twenty wavelength channels of a C-band wavelength-division multiplexed optical ring network, each carrying 10 Gbit/second data concurrently, with 15 mW electrical power consumption (no temperature control required). A convenient pulsed driving scheme is demonstrated and eye patterns and bit-error rate measurements are shown. An algorithm is developed to measure the power-division ratio between the two output ports, the insertion and switching losses, and non-ideal phase deviations.

  15. For example, by examining the expression for ‘baroff’ in Eq. (2) in the simple case when δ0= 0, we see that −t2+ |κ|2(for |κ| > 0.5 and t < 0.5) and +t2 − |κ|2 (for |κ| < 0.5 and t > 0.5) give the same numerical value.
