Measurement of chromatic dispersions in Ti-diffused LiNbO(3) optical waveguides

Chromatic dispersion properties of the Ti:LiNbO(3) optical waveguide have been investigated. Dispersion values of the waveguide fabricated in Z-cut LiNbO(3) were sigma(TE) = -2.0 fsec cm(-1) nm(-l) at a wavelength of 1.3 microm and sigma(TE) = -1.3 fsec cm(-1) nm(-1) at a wavelength of 1.5 microm. Measurement results were compared with theoretical values that take into account the bulk dispersion data and the waveguide dispersion characteristics.
