Highly nonlinear composite chalcogenide/polymer fibers
22 June 2003
Composite As2Se3/PES (polyethersulfone) fibers have been fabricated that have As2Se3 core diameters between 0.5 and 3 microns surrounded by a PES cladding approximately 50 to 150 microns in diameter. The very small core areas along with the large Kerr and Raman coefficients found for As2Se3 make these fibers excellent candidates for low cost nonlinear devices.
