Abstract: Chalcogenide 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. Here we demonstrate the
viability of two complementary soft lithography methods for patterning and
integrating chalcogenide glass waveguides from solution. One method,
micro-molding in capillaries (MIMIC), is shown to fabricate multi-mode
As2S3 waveguides which are directly integrated with quantum cascade lasers
(QCLs). In a second method, we demonstrate the ability of micro-transfer
