Abstract
Waveguide connectors include a ferrule having first alignment features. A polymer waveguide has one or more a topclad portions, each with a waveguide core, second alignment features fastened to the first alignment features, and underclad portion that is thicker than the one or more topclad portions. The polymer waveguide has a higher coefficient of thermal expansion than the ferrule and is fastened to the ferrule under tension.
