Control of dispersion in photonic crystal waveguides using group symmetry theory
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-error optimisation of the design parameters. A family of dispersion curves is generated by controlling a single geometrical parameter.
This concept is demonstrated experimentally with very good agreement with theory.
