Abstract
The invention provides a low stress optical waveguide assembly wherein one or more waveguide cores have a conformal cladding in register the waveguide core. The core and cladding are preferably lithographically formed on a substrate. A connector assembly provides for the precision interconnection of mating arrays of parallel optical waveguides. The connector assembly has a base with several parallel channel walls cut along a surface of the base. A waveguide assembly is positioned on the base. The waveguide assembly comprises a substrate and one or more transparent, polymeric waveguides on and raised from a surface of the substrate. A conformal cladding is in register with the waveguide core. Such conformal cladding contributes to a reduction in waveguide stress. The waveguide assembly is positioned on the base such that each of the waveguides is set in one of the channels and contacts the walls of the channel. A cover plate holds the waveguide assembly on the base.
