Abstract :
The excess loss in a right-angle X junction composed of weakly-guiding singlemode buried channel waveguides is quantified numerically and shown to be consistent with a simple physical model based on a Gaussian approximation to the fundamental mode and Fresnel diffraction across the junction.
