Abstract :
A novel method to compensate dispersion and dispersion slope at the same time by using fiber Bragg grating written on the tapered core fiber has been presented. The fabrication method about this kind of tapered core fiber has been realized by precisely controlling the fiber´s diameter during the process which is drawing the preform into optical fiber. The fiber grating written on this kind of fiber has parameter as 3dB bandwidth 0.861nm. Its dispersion value is −1159ps/nm (within 0.8nm bandwidth), and the dispersion slope is −1.3 ps/nm2. These characteristics of the grating make it can be used in high speed optical fiber communication systems which need the dispersion and dispersion slope be compensated at the same time.
