Abstract
We explore an approach to multiport, phase-insensitive all-optical switching of milliwatt power signals based on linear coupling in cascaded directional couplers and on nonlinear parametric gain via the second-order nonlinearity. For the basic unit, a two-core coupler, we experimentally demonstrated ultrafast transparent switching of 1550 nm signals triggered by 5-ps-long control pulses at approximate to 775 nm with a peak power of 1.3 W. Theoretically, we show that this concept has the potential for terabit/s switching with a few picojoules control energy and without pulse degradation.
