利用群对称理论控制光子晶体波导的色散

Control of dispersion in photonic crystal waveguides using group symmetry theory

Pierre Colman, Sylvain Combrié, Gaëlle Lehoucq, Alfredo De Rossi

摘要:

通过耦合线缺陷光子晶体波导中的奇模和偶模来实现色散剪裁。耦合确定从头使用群论分析,而不是通过试验和错误优化的设计参数。通过控制单个几何参数,生成一系列色散曲线。在1.5mm长的波导上进行了实验验证,与理论结果符合得很好。

英文摘要:

We demonstrate dispersion tailoring by coupling the even and the odd modes in a line-defect photonic crystal waveguide. Coupling is determined ab-initio using group theory analysis, rather than by trial and error optimisation of the design parameters. A family of dispersion curves is generated by controlling a single geometrical parameter. This concept is demonstrated experimentally on 1.5mm-long waveguides with very good agreement with theory.
