Abstract
Optical components fabricated from diblock, triblock, or multiblock copolymers, and particularly a waveguide wherein the optical field intensity (OFI) of a guided wave is tailored by selecting block copolymers, or block copolymers in combination with homopolymers, with components having different molecular weights and refractive indices, and treating the block copolymer by processing to produce phase separations which form unique morphologies controlling the shape, size, and spacing of the layers, to achieve concentration of the OFI in selected portions of the waveguide.
