A geometrically shaped optical waveguide crossing with minimal transmission loss is described. A symmetrically tapered waveguide intersection is used to minimize loss in the intersecting region where at least two optical waveguides cross one another. The present invention embodies a waveguide crossing that includes tapering the width of the waveguides as they approach the intersecting region, forcing the field of light to contract, reducing asymmetric field distortions, and thus reducing transmission loss and effectively minimizing crosstalk. This is accomplished by focusing light through a perpendicular or near perpendicular intersection by simple linear tapering rather than by the use of a lens or other previously used devices.
