Abstract
A capillary electrophoresis device having a substrate layer and a cover layer, with a plurality of electrophoresis channels formed in the substrate layer, includes an optical waveguide system that transmits excitation radiation from a source port into each one of the electrophoresis channels. The optical waveguide system is defined by regions, within either the cover or substrate, that have an index of refraction higher than that of the surrounding material.
