Abstract
An optical waveguide coupler made by integrated optical circuit techniques is employed to direct light from a document to be copied to a line of photosensors of a large scale integrated photosensor module. A plurality of optical waveguides are spaced widely along the document and closely along the photosensor array. Spaced channels are formed in a higher refractive index glass layer on a glass substrate. The higher index layer glass provides the plurality of optical waveguides separated by the channels.
