Chalcogenide fibers used in our experiments are formed from very high purity materials in order to achieve single mode fibers with relatively low losses of approximately 0.5 dB/m. All-optical processing devices typically require a nonlinear phase shift /spl Delta//spl Phi/=/spl gamma/PL=/spl pi/ radians for an optical pulse propagating with a peak power P through a fiber length L. The nonlinear fiber response is measured by /spl gamma/=2/spl pi/n/sub 2///spl lambda/A/sub eff/, where n/sub 2/ is the nonlinear Kerr coefficient, /spl lambda/ is the wavelength and A/sub eff/ is the effective core area. Our experiments demonstrate /spl gamma/=1500 W/sup -1/km/sup -1/ for core areas of 50 /spl mu/m/sup 2/. We measure strong self-phase modulation in As-Se fibers formed from high purity materials. Raman gains near 40% were measured using a CW pump power near 200 mW in a 70 cm long fiber with a core area of 50 /spl mu/m/sup 2/. Applications of these fibers to Raman and parametric amplifiers as well as optical processing devices will be discussed.
