Evolution of silica-based highly nonlinear fibers for FWM-based wavelength conversion application
Recent progresses on silica-based highly nonlinear fibers for practical FWM-based applications such as wavelength conversion efficiency enhancement and chromatic dispersion design are described, and then functional wavelength conversions using the fibers are demonstrated.
Silica-based highly nonlinear fiber with /spl gamma/ = 30/W/km and its FWM-based conversion efficiency
Silica-based highly nonlinear fiber with a record-breaking /spl gamma/ of 30 /W/km has been fabricated. FWM-based conversion efficiency was evaluated and we have confirmed that the new fiber shows the highest efficiency among fibers composed of various materials.
Nonlinear optical properties of As-Se fiber
Large optical Kerr nonlinearities in low linear loss As-Se glass fibers are shown to have potential for ultra-fast, low power, all-optical processing applications. Nonlinear phase shifts near tc radians are demonstrated in fibers only 60 cm long.
