Paper Abstract

Wideband optical waveguide phase modulator is a basic device in high speed or coherent optical fiber communication system. Because of the limit from electrode capacitance, conventional modulators based upon standing wave voltage E / 0 modulation hardly get the bandwidth as wide as several GHz. This paper presents an optical waveguide phase modulator, which takes the advantage of travelling-wave modulator. Its 3dB bandwidth of phase modulation index (5 (peak to peak value) has reached 6 GHz, while the total insertion loss is moderately 5dB in all over the band.
