Resonant optical tunnelling in planar three-layer photonic microstructures
Yago Arosa, Alejandro Doval, Raúl de la Fuente
We present a unified analytical framework for resonant optical tunnelling in three-layer photonic systems embedded in a transparent dielectric medium. Compact expressions for the t…

Coupled surface plasmon and resonant optical tunnelling in symmetric optical microcavities
Alejandro Doval, Yago Arosa, Raúl de la Fuente
A symmetrical structure consisting of a low refractive index dielectric layer between two metallic films, i.e. an optical cavity, surrounded by a semi-infinite dielectric medium of…

Modelling resonant transmission in a Fabry-Perot/Surface-Plasmon microcavity
Yago Arosa, Alejandro Doval, Raúl de la Fuente
Coupled surface plasmons arise in the surfaces of a dielectric layer between two metallic media when a dim wave propagating in the dielectric generates resonant free charge oscilla…
