Kiani, Leily S.; Dawson, Jay W.; Drachenberg, Derrek R.; Messerly, Michael J.; Pax, Paul H.

A non-radial array of microstructure elements provides enhanced wavelength selective filtering. The elements are arranged along a line that does not intersect the center of the core. In this configuration, the first coupling element in an array that is nearest to the core is a non-integer array unit spacing from the main waveguide where the array unit spacing is defined as the flat to flat distance of a hexagonal cell.
