Extensive Q-factor tuning for leaky modes with minimal frequency variation in asymmetric slab grating structures

Extensive Q-factor tuning for leaky modes with minimal frequency variation in asymmetric slab grating structures

Abstract We investigated an asymmetric slab grating structure to achieve significant tuning of the quality (Q) factor for a leaky mode while minimizing frequency variation. This structure comprises two identical gratings placed on the top and bottom of a slab waveguide, with one grating laterally sh...
