In order to observing a waveform of a high symbol-rate optical signal, all optical signal sampling technique using a periodically poled LiNbO3 (PPLN) wavelength converter is experimentally investigated. An optical gate is realized by a chirped PPLN having 2.2-nm QPM wavelength range where caused difference frequency generation between a high symbol rate optical signal and short pulses for sampling. An experiment of optical signal sampling is carried out by injecting an optical pulse train with 2.8-ps time width and an 160 Gb/s signal to the PPLN thus basic operation of the proposed scheme is confirmed.
