ABSTRACT:
An optical intersection with reduced transmission loss is described. An embodiment of the inventive interconnection comprises two intersecting waveguides. According to the teachings of the invention, deleterious asymmetric field distortions in the waveguides, associated with the presence of the adjacent waveguides, are reduced by, for example, changing the width of the intersection region, and the widths of the waveguides as they approach the intersection region.
