When Reflection and Transmission Amplitude Coefficients Exceed Unity: Evanescent Waves, Resonances, and Optical Modes
Raúl de la Fuente
The reflection and transmission of propagating harmonic waves in linear optical systems have been widely discussed in the literature and are generally well understood. In passive s…
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…
Beneath and beyond frustrated total reflection: a practical demonstration
Carolina Filgueira-Rama, Alejandro Doval, Yago Arosa +1
Frustrated total internal reflection is analyzed from an unusual point of view Unlike most similar works, incident angles are used here as the scanning variable, instead of the tun…
Refractive index measurements in absorbing media with white light spectral interferometry
Yago Arosa Lobato, Elena Lopez Lago, Raul de la Fuente Carballo
White light spectral interferometry is applied to measure the refractive index in absorbing liquids in the spectral range from 400 to 1000 nm. We analyze the influence of absorptio…
Spectrally resolved white light interferometer for measuring dispersion in the visible and near infrared range
Y. Arosa, E. Lopez Lago, R. de la Fuente
We design a spectrally resolved interferometer to measure the refractive index of transparent samples over a broad spectral range between 400 and 550 nm. The measuring device consi…
Modeling the Temperature-Dependent Material Dispersion of Imidazolium-Based Ionic Liquids in the VIS-NIR
Y. Arosa, B. S. Algnamat, Rodriguez Fernandez C. D. +3
A thorough analysis of the refractive index of eleven 1-alkyl-3-methylimidazolium-based ionic liquids with three different anions, tetrafluoroborate bis(trifluoromethylsulfonyl)imi…
Fresnel coefficients, coherent optical scattering and planar waveguiding
Alejandro Doval, Carlos Damián Rodríguez-Fernández, Héctor González-Núñez +1
One-dimensional optical waveguiding is revisited using the electromagnetic deduction of Fresnel formulas relating the incident, reflected, and transmitted waves on the abrupt inter…
Accuracy of Refractive Index Spectroscopy by Broadband Interferometry
Yago Arosa, Carlos Damián Rodríguez-Fernández, Alejandro Doval +2
Uncertainties of refractive and group index in dispersion measurement by spectrally resolved white light interferometry are deeply analyzed. First, the contribution to uncertainty…
