Abstract
An all-optical switching device consisting of a LiNbO3 waveguide Mach-Zehnd er interferometer with a quasi-phase-matched sum-frequency generation (QPM- SFG) section, and a thermooptic phase shifter in the arms was designed and fabricated. Picosecond gate switching of signal wave by control pulses both in 1.5-mum wavelength band is demonstrated in a device having a QPM-SFG se ction of 5-mm length.
