Abstract
A fully additive method for forming optical waveguides and devices, such as thermo-optic polymer switches and electro-optic polymer modulators, is disclosed. A first polymer material of refractive index Nis coated onto a suitable substrate to form a first cladding layer. The first cladding is then selectively patterned using a mold to form an impression of the waveguide core into the first cladding layer. Next, a core layer is formed by ink-jet printing onto the imprinted first cladding layer with a core material of refractive index N(N>N). The core layer is subsequently coated by ink-jet printing with a second polymer material of refractive index N(N<N) to form a second cladding, resulting in an optical waveguide. An electrode may be ink-jet printed before coating the first cladding material or after coating the second cladding material, or both before and after coating, in order to form active photonic devices.
