Course Instructor
SC480: Infrared Fiber Optics
Infrared (IR) fiber optics transmitting wavelengths beyond 2 mm are useful in sensor, IR laser power delivery, and fiber amplifer applications. This course will provide attendees a basic understanding of the three categories of IR fibers; fluoride and chalcogenide glass fibers, poly and single-crystalline fibers, and hollow waveguides. Specifically, the course will cover IR fiber fabrication techniques, including drawing and extrusion, the optical and mechanical properties of fibers, and current and future applications of these unique fibers. Emphasis will be placed on the IR optical materials that have today been fabricated into the best IR fibers. In particular, the best glass fibers are made from the heavy metal fluoride and chalcogenide glasses while the polycrystalline silver halide and single-crystal sapphire materials have been fabricated into the most promising crystalline fibers. Hollow waveguides with metallic/dielectric coatings and new IR photonic bandgap structures will also be discussed. Finally, many examples will be given of the use of IR fibers in sensor applications, such as chemical analysis, radiometry, and imaging, laser power delivery for laser surgery and industrial cutting and welding, and IR fiber amplifiers.
