Design of high-Q Cavities in Photosensitive Material-based Photonic Crystal Slab Heterostructures

摘要

We propose a novel concept for creating high-Q cavities in photonic crystal slabs (PCS). We show that photonic crystal slab-based double heterostructure cavities, formed by variations in the refractive index, can have large a Q-factor (up to Q=1×106), and that such cavities can be implemented in chalcogenide glasses using their photosensitive properties.
