Charcogenide glass materials exhibit a variety of optical
properties that make them desirable for near- and mid-infrared communications
and sensing applications. However,
processing limitations for these photorefractive materials have made the direct
integration of waveguides with sources or detectors challenging. Present methods of waveguide
fabrication, including fiber drawing, direct write, and chemical etch or dry
etch, can only reliably produce waveguide on flat substrates.
at Princeton University have developed multiple solution-based soft lithography
methods for patterning and
integrating chalcogenide glass structures onto both flat and curved
substrates. These methods form a
suite of processes that can be applied to chalcogenide materials to create a
diverse array of 2D or 3D mid-IR optical and photonic structures ranging from
<5 to 10¿s of mm in dimension.
