Paper Abstract

The guided mode resonance (GMR) phenomena has been studied and exploited for applications in sensors, polarizers, dichroic laser mirrors, and more. These micro-optical structures serve as highly functional devices capable of narrowband spectral filtering. Their relatively simple design includes a subwavelength periodically modulated index layer and a waveguiding layer. This configuration yields efficient and easily tunable devices over a broad range of wavelengths. Currently GMR filters have been fabricated exclusively on flat surfaces. In this paper, we demonstrate fabrication of GMR filters on conformal surfaces using non-traditional techniques. Flexible molds are used as replication templates in a micro-transfer molding process. SU-8 negative photoresist serves as the molded polymer with good thermal characteristics compatible with subsequent deposition of dielectric layers. Fabrication procedures for GMR filters at near-IR wavelengths on concave lens surfaces are discussed, and initial experimental results are presented.
