Abstract
A method of making chalcogenide based polymeric materials and converting those materials into optical fiber preforms and polymeric optical fibers. The preforms and fibers comprise chalcogenide elements and crosslinking moieties. These fibers can be used as optical waveguides at infrared wavelengths where other polymer fibers do not operate. The optical waveguides are ideally suitable for applications requiring the transmission of low-power infrared light, but may also be useful for transmitting high-power light at visible or infrared wavelengths.
