Claim 8:
9. An optical splitter, comprising:
an input waveguide having a high V number in a first dimension, a low V number in a second dimension and configured to input a wavelength range of light;
a slab waveguide with an input edge and an output edge, the slab waveguide optically coupled to the input waveguide and configured to receive light from the input waveguide; and
an array of output waveguides positioned across the output edge of the slab waveguide such that some of the output waveguides are center channel output waveguides and others of the output waveguides are outer channel output waveguides, wherein the array of output waveguides comprises:
a center channel waveguide having a first width;
a first pair of adjacent outer channel waveguides each having a narrower width than the first width, wherein the first pair of adjacent outer channel waveguides is positioned to receive a summed optical power that is approximately the same as an optical power received by the center channel waveguide.
