Abstract:
1. A method of forming an optical waveguide structure, comprising: providing a first material layer having a first refractive index and comprising a polymer matrix, at least one monomer compatible with the polymer matrix, a procatalyst, and a cocatalyst, where the polymer matrix has a form of the first material layer in a solid phase, the at least one monomer, procatalyst and cocatalyst are dispersed in the first material layer of the polymer matrix, the polymer matrix and at least one monomer have different refractive indices, the cocatalyst is suitable for converting the procatalyst to a latently active form upon exposure to actinic radiation, and the latently active form is convertible to an active form upon heating to a first temperature; selectively exposing a first portion of the first material layer to the actinic radiation; and first heating the first material layer to the first temperature, the first refractive index changing to a second refractive index.
