S. Kawanishi et al., High sensitivity waveform measurement with optical sampling using quasi-phasematched mixing in LiNBO3 waveguide, ELECTR LETT, 37(13), 2001, pp. 842-844
High efficiency (1.7 x 10(-2) W-1) waveform measurement is experimentally d
emonstrated using quasi-phasematched mixing in an LiNbO3 waveguide. A 160 G
bit/s optical waveform is observed with temporal resolution of 3.6 ps.
