摘要：

A LiNbO3 waveguide quasi-phase-matched sum-frequency generation (SFG) device using a fan-out domain-inverted grating for picosecond optical sampling was designed and fabricated. Sampling of signal waves at 1.5-mu m wavelength by 25-ps sampling pulses generated by a gain-switched laser diode is demonstrated in a device of 5 mm length with a normalized SFG efficiency as high as 43%/W.
