Abstract

A method and apparatus are provided for providing an electro-optic interface for exchanging information signals. The method includes the steps of disposing an optical array adjacent a first side of an optically transparent substrate, such that a plurality of transmission paths of the optical array pass directly through the substrate, applying an optically transparent underfill between the substrate and adjacent optical array with the plurality of transmission paths of the optical array passing directly through the underfill and coupling a plurality of optical signals of the optical array through the optically transparent underfill and optically transparent substrate between the optical array and an optical connector.
