Abstract:
1. A chalcogenide glass optical fiber comprising a central opening for passing light therethrough, a chalcogenide microstructured region disposed around said central opening, and a solid chalcogenide region disposed around said microstructured region for providing structural integrity to said microstructured region; said microstructured region of said fiber has outer diameter in the approximate range of 80-1000 μm; said central opening is at least about 1 μm wide; and said microstructured region is 5-500 μm thick and comprising a plurality of openings arranged in courses with the openings disposed from each other a distance in the approximate range of 1-12 μm and the arrangement of said openings is such as to yield a photonic band gap in the infrared beyond about 2 μm wavelength.
