Generalized non-Hermitian Hamiltonian for guided resonances in photonic crystal slabs [PDF]
NanophotonicsWe develop a generalized non-Hermitian Hamiltonian formalism for guided resonances in photonic crystal slabs, derived directly from Maxwell’s equations through a systematic guided-mode expansion.

Silicon nanocrystal-based photonic crystal slabs with broadband and efficient directional light emission [PDF]
Scientific Reports, 2017 Light extraction from a thin planar layer can be increased by introducing a two-dimensional periodic pattern on its surface. This structure, the so-called photonic crystal (PhC) slab, then not only enhances the extraction efficiency of light but can ...
