Design Guidelines for Ultra-broadband Dispersion-flattened Optical Fibres with Segmented-core Index Profile
نویسندگان
چکیده
Single optical fibres exhibiting minimum dispersion over the two optical wavelength windows of 1300 and 1550 nm region are essential for the multi-channel operation of dense wavelength multiplexed systems and networks. Design guidelines of dispersion-flattened optical fibres, over a wide band of optical spectrum, which have a triple-clad or segmented-core distribution of stepindex regions are developed in order to predict the dispersion curves representing the waveguide dispersion parameter and to adjust the dispersion flattening effect of triple-cladded index profile fibres. The flattening covers a wavelength range of more than 350 nm is achievable. The effects of the geometrical and index distribution parameters of the triple-clad to the characteristic of the total dispersion of the fibre are analysed. The guidelines are simple and logical for determining the main parameters and their sequence for tailoring the fibre dispersion characteristics and would be useful for systems engineers in understanding the fibre design process in the ultra-boradband optical networks.
