Title:
METHOD FOR DESIGNING THE LAYOUT OF A PLURALITY OF OPTICAL WAVEGUIDES
Document Type and Number:
WIPO Patent Application WO/2011/077873
Kind Code:
A1
Abstract:
Disclosed is a method for optimally designing a layout for a plurality of optical waveguides in which the optical waveguides are configured in a planar configuration that creates one or more intersections. Each of a plurality of waveguides bundled at the input end are branched into two, and a plurality of default routes are set for all of the plurality of the waveguides, such that a given branched waveguide forms at least one intersection with other branched waveguides, and such that the branched plurality of waveguides can be bundled at least at two or more separate places on the output end. The intersections that exist in a route are counted, and a default value (branching ratio) for a cross-section (thickness, shape) is set for a given waveguide and each of a plurality of waveguides branched from the waveguide, on the basis of the number of intersections that were counted.
