Abstract :
An electro-optic (EO) phase modulator with a low driving voltage that uses newly developed KTa/sub 1-x/Nb/sub x/O/sub 3/ buried waveguides is described. The waveguide layers for the core and cladding were formed using liquid phase epitaxy techniques. The propagation loss was less than 0.5 dB/cm and the polarisation-dependent loss was less than 0.1 dB/cm. The EO phase modulator had a low V/sub (pi)/*L value of <1.5 cm V (4.0 V biased potential) and a fast response of 3 GHz.
