@ARTICLE{Mansouri-Birjandi, author = {Jafari, Esmat and Mansouri-Birjandi, Mohammad Ali and }, title = {Wideband Dispersion Compensation in Hexagonal Lattice Photonic Crystal Fiber}, volume = {12}, number = {2}, abstract ={In this paper, a new structure is provided for the dispersion compensating photonic crystal fibers in order to broaden the chromatic dispersion and increase the dispersion compensating capability in a wide wavelength range. In the structure, putting elliptical holes in the first ring of the inner core clad of a dispersion compensating fiber of the hexagonal lattice, increases the wavelength range of the dispersion compensation, and causes this fiber to have the capability of dispersion compensation in the whole E to U telecommunication bands. In this fiber, the minimal dispersion will be -1006 ps/(nm.km) at the 1.68 μm wavelength and at the 1.55 μm wavelength the dispersion coefficient will be -710 ps/(nm.km). The simulations are all done using the finite difference time domain numerical method. }, URL = {http://ijop.ir/article-1-304-en.html}, eprint = {http://ijop.ir/article-1-304-en.pdf}, journal = {International Journal of Optics and Photonics}, doi = {10.29252/ijop.12.2.91}, year = {2018} }
