Dispersion tailoring is performed by tuning the structural parameters of the waveguide. Group velocity dispersion is varied between very low values of -1.1 and +3.3 ps/(nm.km) over an approximately 350-nm bandwidth for an optimum structure. Because of ultra-flat group velocity dispersion profile, higher order dispersions are also very low. Real part of nonlinear parameter for the optimum waveguide is 355.6 (W-1m-1) at 1550 nm. Therefore, a good balance between nonlinearity and dispersion is provided that makes the waveguide applicable for highly efficient implementation of nonlinear functions in 1.55-µm wavelength range. %> http://opsi.ir/article-1-237-fa.pdf %P 481-484 %& 481 %! %9 Research %L A-10-1-217 %+ Optoelectronic Research Center, Electrical and Electronic Department, Shiraz University of Technology, Shiraz, Iran %G eng %@ 1126-3278 %[ 2014
