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 N1 is 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 N2 (N2>N1). The core layer is subsequently coated by ink-jet printing with a second polymer material of refractive index N3 (N3

Abstract: The present invention is a three-dimensional tapered waveguide coupler capable of interconnecting electro-optical devices with differing optical mode profiles. The ends of the waveguide are configured to match the optical mode profiles of the electro-optical devices that the waveguide interconnects. The waveguide adiabatically transmits the fundamental mode of the photo-optic signal from the electro-optical device at the waveguide's input end to a different electro-optical device at the waveguide's output end. A single coupler can be configured with one or more waveguides, each waveguide having different optical mode profiles at either end and different optical transmission characteristics.
