Optimization, tolerance analysis and implementation of a Stokes polarimeter based on the conical refraction phenomenon
(Optical Society of America, 2015-03)
Recently, we introduced the basic concepts behind a new polarimeter device based on conical refraction (CR), which presents several appealing features compared to standard polarimeters. To name some of them, CR polarimeters ...
Interferometric characterization of the structured polarized light beam produced by the conical refraction phenomenon
(Optical Society of America, 2015-07)
The interest on the conical refraction (CR) phenomenon in biaxial crystals has revived in the last years due to its prospective for generating structured polarized light beams, i.e. vector beams. While the intensity and ...

Non-linear excitation of polariton cavity modes in ZnO single nanocombs
(Optical Society Of America, 2014-02)
Tunable second harmonic (SH) polaritons have been efficiently generated in ZnO nanocombs, when the material is excited close to half of the band-gap. The nonlinear signal couples to the nanocavity modes, and, as a result, ...
An auditory illusion of proximity of the source induced by sonic crystals
(Public Library of Science, 2015-07)
In this work we report an illusion of proximity of a sound source created by a sonic crystal placed between the source and a listener. This effect seems, at first, paradoxical to naïve listeners since the sonic crystal is ...
O ensino de isomeria óptica por meio de atividades experimentais
(Universidade Federal de Santa MariaBrasilBioquímicaUFSMPrograma de Pós-Graduação em Educação em Ciências: Química da Vida e SaúdeCentro de Ciências Naturais e Exatas, 2017-02-22)
In order to contribute to the teaching and learning of chemistry, this research is presented and it proposes an alternative methodology to the study of scientific concepts in optical isomerism. The choice of this subject ...
