Abstract
We report picosecond all-optical switching in optical communication band using a LiNbO3 waveguide quasi-phase matched second-harmonic generation/difference-frequency generation device. Analysis based on the beam propagation method showed that 1 ps switching with 3.1% efficiency is feasible with 10 W peak control pulse power. Switching efficiency of −22 dB was demonstrated using control pulses of 10 ps width and 2 W peak power.
