There are great opportunities for advancement in the realm of infrared (IR) optics through the use of chalcogenide glasses (ChGs). The development of IR optics using ChGs is important for applications in search and rescue operations, firefighting efforts, medical imaging, and satellites. Instead of creating bulky, expensive, single crystal IR glasses, ChGs can be deposited as thin films by solution derived (SD) spin or dip coating. Our research takes a multidisciplinary approach to investigate ChGs thin films using physics, chemistry, optics, and materials science.
Investigation Of Spin And Dip-Coating Phase Change Chalcogenide Materials As A Novel Technique For Coating And Functionalizing Conformal Optics, Paul Vecchio
Physics and Astronomy Summer Fellows
Chalcogenide glasses (ChGs) have excellent infrared (IR) transparency ranging up to 20 μm, large nonlinear refractive indices, and tailorable thermo-optic coefficients (dn/dT) that have great potential for applications in detectors, sensors, waveguides, imaging devices, photonic waveguides, acousto-optics, and optical devices. Spin and dip coating ChGs from solution is a low-cost, simple, and scalable method for depositing films over a large area. In this study, we utilize the novel approach of spin and dip coating to create thin ChG films of arsenic trisulfide (As2S3) and arsenic selenide (As2Se3). To realize the full potential …
