The Optical Power Distribution and Scattering Losses in Symmetric Channel Waveguide X-Junction
Journal article, 1991

It is shown theoretically and experimentally that there is sufficient light radiation at the crossing points of wave-guides, and sufficient coupling between input branches and output branches of integrated optic symmetric crossing channel wave-guides. For straight X-junctions the crosstalk could be changed in a wide range varying the crossing angle, while for widened X-junction with a fixed crossing angle the crosstalk could be changed by varying the length of the central straight waveguide section.
