Abstract: |
|
A new design of hexagonal-lattice photonic crystal fiber, with solid core is proposed for study of dispersion and confinement loss for optical communication. The fiber has five air-hole rings, yet the diameter of air holes is different in their structures. In this work we observed the effect of varying d1 (diameter of inner two rings) keeping d2 constant, effect of varying d2 (diameter of outer three rings) keeping d1 constant and the variation of lattice constant Ʌ on dispersion and confinement loss, and it is found that the effect of varying d1 has a greater effect on dispersion in comparison with confinement loss and altering d2 has no significant effect on dispersion but have greater effect on confinement loss. Finite-difference time domain (FDTD) method is used for simulation. |
