Zero-chirp broadband Z-cut Ti:LiNbO/sub 3/ optical modulator using polarization reversal and branch electrode

In this paper, a novel zero-chirp Z-cut LiNbO/sub 3/ optical modulator using ferroelectric polarization reversal and a branch electrode is proposed. The optical modulator with a Ti-diffused optical waveguide had a very small chirp parameter, which was less than 0.02. The performance showed a preferable 10-Gb/s eye opening and bias stability.
