Chalcogenide Glass Thin-Film and Fiber Structures for Chemical and Biological Sensing

Chalcogenide (ChG) glasses are well known for their high infrared (IR) transparency and amenability to fabrication in iber and thin ilm forms, which makes them attractive candidates for mid-IR optical chemical and biological sensors. This chapter describes recent advances in the production of sensing devices from a variety of thin-ilm and iber structures, highlighting the critical material parameters needed for achieving low-loss, high-detectivity operation.
