Abstract

An electric field assisted two-step ion migration process in soda-lime glass plates has been used to produce optical couple waveguides with semicircular and circular cross sections. The radius and the numerical aperture of the guides are approximately the same as those of the graded index multimode fibers. A new coupler structure, the edge reflecting element, which could be used as an integrated demultiplexer in wavelength division multiplexing, has been fabricated. The loss spectrum of the waveguides is analyzed and a theoretical treatment of the ion concentrations is given.
