Composite As2Se3/polyethersulfone fibers are fabricated that have As2Se3 core diameters between 0.5 and 3 microns surrounded by a PES cladding 50 to 150 microns in diameter. The small core areas along with the large nonlinear coefficients found for As2Se3 make these fibers excellent candidates for compact low-cost nonlinear devices.
