High sensitivity waveform measurement with opticalsampling using quasi-phasematched mixing in LiNbO 3 waveguide

Abstract
High efficiency (1.7 × 10-2 W-1) waveform measurement is experimentally demonstrated using quasi-phasematched mixing in an LiNbO3 waveguide. A 160 Gbit/s optical waveform is observed with temporal resolution of 3.6 ps.
