Photon-Mediated Interactions near a Dirac Photonic Crystal Slab [PDF]

ACS Photonics, 2021
Las dispersiones de energía de Dirac son responsables de las extraordinarias propiedades de transporte del grafeno. Esto motivó la búsqueda de la ingeniería de tales dispersiones de energía también en la fotónica, donde se ha predicho que conducirán a muchos fenómenos emocionantes.

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.

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 ...

Guiding mechanisms in dielectric-core photonic-crystal optical waveguides [PDF]

, 2001
We show that the main guiding mechanisms in dielectric-core photonic crystal optical waveguides are total internal reflection and distributed Bragg reflection.

Modal reflectivity in finite-depth two-dimensional photonic-crystal microcavities [PDF]

, 1998
We present finite-difference time-domain calculations of the Q factor for an optical microcavity defined by a slab waveguide and two-dimensional photonic-crystal end mirrors.

A photonic crystal nanocavity laser in an optically very thick slab [PDF]

, 2011
A photonic crystal (PhC) nanocavity formed in an optically very thick slab can support reasonably high-Q modes for lasing. Experimentally, we demonstrate room-temperature pulsed lasing operation from the PhC dipole mode emitting at 1324 nm, which is ...

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
