Abstract:
An optical device for transmitting at least one input light beam, said device comprisinga) a substrate; b) a lower cladding layer on said substrate; c) an optical waveguide on the lower cladding layer, said optical waveguide having a non-linear polymer core region and a linear polymer core region that the input light beam traverses, said non-linear polymer core region exhibiting a greater change in its refractive index under an applied stimulus than that exhibited by the linear polymer core region; and d) an upper cladding layer disposed on the optical waveguide and the lower cladding layer, wherein the lower and upper cladding layers have refractive indices that are lower than the refractive indices of the linear polymer and the nonlinear polymer and wherein said non-linear polymer core region comprises a thermooptic polymer.
