Solid Microstructured Chalcogenide Glass Optical Fibers for the Near- and Mid-Infrared Spectral Regions

This paper demonstrates a new and flexible route to microstructuring of chalcogenide glass fiber for operation in the near- to mid-infrared, presenting an alternative to air-glass microstructuring. For the first time, a one-layer, solid microstructured optical fiber is successfully drawn from As
