Normal incidence narrowband transmission filtering in zero-contrast gratings
Xuan Cui, Hao Tian, Yan Du +3
We report narrowband transmission filtering based on zero-contrast grating (ZCG) reflectors at normal incidence. Computational results show that the filtering is realized through s…

Broadband high reflectivity in subwavelength-grating slab waveguides
Xuan Cui, Hao Tian, Zhongxiang Zhou
We computationally study a subwavelength dielectric grating structure, show that slab waveguide modes can be used to obtain broadband high reflectivity, and analyze how slab wavegu…
