Abstract:A wavelength converter based on the self phase modulation(SPM) effect in highly nonlinear microstructure fibers(MFs) is proposed.The core diameter and the pitch of the fiber are 2.05 μm and 5.0 μm,respectively,and the diameter of the airholes in the fiber cladding is 4.50 μm.The calculating nonlinear coefficient is 112.2 W-1 km-1 and it is 11 times higher than that of a conventional dispersion-shift fiber and 56 times higher than that of a conventional single-mode fiber.The length of the fiber i...
