Abstract

For the high-speed and wideband operation, the traveling-wave structure has been developed for guided-wave modulators. Applying the asymmetric stripline as electrodes, the frequency response of the LiNbO₃ waveguide modulators has been smoothed over. The operation bandwidth has been expanded up to 18 GHz[1] and a temporal pulse waveform less than 50 ps created by the modulator has already been observed by the streak camera[2].
