22 February 2008 Review: fine embossing of novel glasses for photonic integrated circuits
Author Affiliations +
Hot embossing of novel inorganic-compound glasses is a new fabrication technology for guided wave devices and circuitry. A patterned mould is pressed into the glass above its glass transition temperature (Tg) and replicated; cooling below Tg freezes-in the required pattern. The state-of-the-art is reviewed. Better than 0.1 μm -scale replication is shown for chalcogenide glasses and fabrication of a hot embossed monomode waveguide demonstrated.
