1. An optical power splitter for distributing light from an optical source to a plurality of optical waveguides, the splitter comprising a slab region and an array of output waveguides attached thereto, wherein the optical source launches a substantially annular beam directly into the slab region, and wherein the beam diffracts with an optical field that is substantially uniform in the plane of the slab region such that, when the optical field in the slab region impinges on the output waveguides, the integral of the optical field over the waveguide cross-sectional area is substantially equal for each output waveguide.
