Abstract:
1. A method for making an optical device structure, the method comprising: disposing a blend between a first cladding having a first refractive index and a second cladding having a second refractive index to form a layered structure comprising the first cladding, the second cladding and a core having a third refractive index, wherein the blend comprises a polymerizable monomer, and wherein the first and second refractive indices are lower than the third refractive index; masking the layered structure with a pattern to define a waveguide area and a surrounding area; irradiating the layered structure via the pattern with radiation to create the waveguide area and the surrounding area in the core, wherein the step of irradiating promotes polymerization of the polymerizable monomer; and processing the layered structure to form the optical device structure, wherein the optical device structure comprises: a first diffusion region disposed between the core and the first cladding; and a second diffusion region disposed between the core and the second cladding, wherein the first and second diffusion regions are disposed on opposite top and bottom sides of the core.
