Effect of Dispersion on Dispersive Wave Generation in Photonic Crystal Fibers

Journal of infrared, millimeter and terahertz waves (impact factor: 0.74). 04/2012; 30(6):580-588. DOI:10.1007/s10762-009-9482-x

ABSTRACT A theoretical investigation on the nonlinear pulse propagation and the influences of the dispersion effect on the dispersive
wave generation in photonic crystal fibers is presented. By simulating the dispersive wave generation under different dispersion
property conditions, it is found the origin of the dispersive wave generation is mainly due to the effect of higher-order
dispersion and the pulse trapping. In addition, we also found that the intensity of the dispersive wave can be further enhanced
by properly modifying the even-order dispersion coefficients to make the pulse trapping developing sufficiently.
