Abstract: The characteristics of Ti: LiNbO3 traveling wave modulator have been analyzed in this paper, taking into account the reflection coefficient of the terminator. The main emphasis of the present work is placed on the description of the effect of the reflection coefficient on the bandwidth, the half-wave voltage and the time domain response. -
