Ym. Choi et al., EXPERIMENTAL MEASUREMENTS AND THEORETICAL COMPARISONS ON THE MODE SIZE OF SINGLE-MODE TI-LINBO3 OPTICAL CHANNEL WAVE-GUIDES, International journal of infrared and millimeter waves, 16(9), 1995, pp. 1561-1571
The modal characteristics of Ti:LiNbO3 optical channel waveguides depe
nd on its fabrication parameters and were determined empirically, The
operating wavelength was 1.55 mu m. Studies and measurements on the mo
de 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 w
ere used to calculate the mode sizes, were good approximations for the
lateral and vertical intensity distributions of the channel waveguide
s respectively. Our experimental results were close to those available
from literature.
