Crossed chiral band approximation for wideband self-collimation of light
JOURNAL OF PHYSICS D-APPLIED PHYSICS(2020)
摘要
We propose a perspective to the evaluation of the wide bandwidth phenomenon for low-symmetric photonic structures, by introducing the band tailoring and chiral band approximation on the self-collimation effect. In the case of the crossing of the bands, we claim the excitation of the lower mode can provide the utilization of the entire bandwidth by suppressing the intersection regions where the frequencies tend to mix. Thereby, we design broadband self-collimation capable, defect-free photonic structures and examine their performances. A fractional bandwidth of 0.35 ( a/lambda=0.429-0.607更多
