Interface mode between gyroelectric and hyperbolic media
Autor: Daniele B. Provenzano, Giuseppe C. la Rocca
We report the prediction of a type of electromagnetic surface wave that propagates at the interface between a gyro -electric material and a hyperbolic medium. By solving Maxwell's equations, the existence conditions of this surface mode are discussed

g-Factor Anisotropy Inversion in InGaAs 2D Nanostructures
Autor: Marcelo Alejandro Toloza Sandoval, Antonio Ferreira da Silva, Giuseppe C. La Rocca, Jhon Elber Leon Padilla, Erasmo A. de Andrada e Silva
The inversion or sign change of the electron g-factor anisotropy in thin-layer semiconductor nanostructures is investigated theoretically and gauged for InGaAs asymmetric single and double quantum wells (QWs). The g-factor anisotropy in these 2D nano

The interplay between interference and absorption leads to interesting phenomena like coherent perfect absorption and coherent perfect transparency (CPA and CPT), which can be exploited for fully optical modulation. While it is known that it is possi

Simulation of the time dependent photoluminescence of a J‐aggregate microcavity
Autor: Paolo Michetti, Giuseppe C. La Rocca
Publikováno v: physica status solidi c. 6:403-406
We have built a model for the optical dynamics of a strongly coupled J-aggregate microcavity. Our model is based on the description of a J-aggregate film as a disordered Frenkel exciton system in which relaxation occurs due to the presence of a therm

Strongly Coupled Organic Microcavities
Autor: Paolo Michetti, Giuseppe C. La Rocca, Leonardo Mazza
Publikováno v: Nano-Optics and Nanophotonics ISBN: 9783662450819
The photophysics of planar microcavities which employ organic materials as the optically resonant medium to achieve the strong-coupling regime is discussed. While as a result of the light–matter coupling, cavity polariton branches appear which are

The spin-dependent quantum transport of electrons in non magnetic III-V semiconductor nanos-tructures is studied theoretically within the envelope function approximation and the Kane model for the bulk. It is shown that an unpolarized beam of conduct

Exciton luminescence polarization decay in type II semiconductor heterostructures
Autor: Giuseppe C. La Rocca, Erasmo A. de Andrada e Silva
Publikováno v: Physica E: Low-dimensional Systems and Nanostructures. 2:839-842
In type II semiconductor heterostructures, one can reduce the electron-hole overlap, without changing much the oscillator strength, so that the space indirect exciton luminescence polarization will decay according to the exciton-bound single-particle
