光子晶体波导中的孤子传输及其延迟特性研究
Soliton pulse propagation and optical delay properties in photonic crystal waveguide
摘要
Abstract
The bright soliton pulse propagation and the slow light delay time properties of 2D cubic and triangular lattice photonic crystal line defect waveguide（PCW） with circular Si-rods near the left edge of the guidedmode are investigated.By using the plane-wave expansion（PWE） method,the ralues of soliton required peak power P0 and delay time TS of the waveguided with different radii of the first two rows of Si-rods adjacent to the waveguide,r1 and r2,and waveguide width D are numerically investigated.Adjusting the waveguide structure can bring in optimized cubic and triangular lattice waveguide,of which P0 is reduced by 81.17% and TS is increased by 66.32% for cubic lattice waveguide;P0 is reduced by 73.7% and TS is increased by 67.63% for triangular lattice waveguide.These results show that the soliton transmission performance in the photonic crystal line defect waveguide can be effectivly optimized.关键词
