Resonance and Bound States in Photonic Crystal Slabs [PDF]

SIAM Journal on Applied Mathematics, 2003
Summary: Using boundary-integral projections for time-harmonic electromagnetic (EM) fields, and their numerical implementation, we analyze EM resonance in slabs of two-phase dielectric photonic crystal materials. We characterize resonant frequencies by a complex Floquet-Bloch dispersion relation \(\omega = W(\beta)\) defined by the existence of a ...

Effects of hydrostatic pressure on the photonic band structure and quality factor of an L3 cavity in a photonic crystal slab

Results in Physics, 2020
In this work, we investigate the effects of hydrostatic pressure on the photonic band structure and quality factor of the fundamental mode in an L3 cavity using the guided-mode expansion method in two-dimensional photonic crystal slabs.

Planar Photonic Crystal Nanocavities with Active Quantum Nanostructures [PDF]

, 2004
Extreme photon localization is applicable to constructing building blocks in photonic systems and quantum information systems. A finding fact that photon localization in small space modifies the radiation process was reported in 1944 by Purcell, and ...

Plasmonic Photonic-Crystal Slabs: Visualization of the Bloch Surface Wave Resonance for an Ultrasensitive, Robust and Reusable Optical Biosensor

Crystals, 2014
A one-dimensional photonic crystal (PhC) with termination by a metal film—a plasmonic photonic-crystal slab—has been theoretically analyzed for its optical response at a variation of the dielectric permittivity of an analyte and at a condition simulating
