Experimental measurements and theoretical comparisons on the mode size of single-mode Ti∶LiNbO3 optical channel waveguides
The modal characteristics of Ti∶LiNbO3 optical channel waveguides depend on its fabrication parameters and were determined empirically. The operating wavelength was 1.55μm. Studies and measurements on the mode size of single-mode Ti∶LiNbO3 optical channel waveguides were made for various fabrication parameters. The two-dimensional mode profiles were studied. The Gaussian and Hermite-Gaussian distributions, which were used to calculate the mode sizes, were good approximations for the lateral and vertical intensity distributions of the channel waveguides respectively. Our experimental results were close to those available from literature.
