Exciton and multiexciton optical properties of single InAs/GaAs site-controlled quantum dots

Canet-Ferrer, J.; Muñoz Matutano, Guillermo; Herranz, J.; Rivas, D.; Alén, B.; González, Y.; Fuster, D.; González, L.; Martínez-Pastor, J. (American Institute of Physics (AIP), 2013-10)

[EN] We have studied the optical properties of InAs site-controlled quantum dots (SCQDs) grown on pre-patterned GaAs substrates. Since InAs nucleates preferentially on the lithography motifs, the location of the resulting ...
Optimización de la profundidad de un reactor fotoquímico solar para tratar aguas de riego

Silvestre Botella, Jordi (Universitat Politècnica de València, 2024-10-02)

[ES] El objetivo de este proyecto es el diseño de un reactor solar para el tratamiento de aguas residuales utilizando el proceso foto-Fenton, el cual se encarga de la oxidación de los contaminantes gracias a la formación ...
Simultaneous guidance of slow photons and slow acoustic phonons in silicon phoxonic crystal slabs

Laude, Vincent; Beugnot, J.C.; Benchabane, S.; Pennec, Y.; Djafari-Rouhani, B.; Papanikolaou, Nikos; Escalante Fernández, José María; Martínez Abietar, Alejandro José (Optical Society of America, 2011)

[EN] We demonstrate theoretically that photons and acoustic phonons can be simultaneously guided and slowed down in specially designed nanostructures. Phoxonic crystal waveguides presenting simultaneous phononic and photonic ...
Spectral decomposition of single-tone-driven quantum phase modulation

Capmany Francoy, José; Fernandez-Pousa, Carlos R. (IOP Publishing, 2011-02-14)

[EN] Electro-optic phase modulators driven by a single radio-frequency tone ¿ can be described at the quantum level as scattering devices where input single-mode radiation undergoes energy changes in multiples of h¿. In ...
Theoretical study about the gain in indirect bandgap semiconductor optical cavities

Escalante Fernández, José María; Martínez Abietar, Alejandro José (Elsevier, 2012-06-15)

[EN] Indirect bandgap semiconductors such as silicon are not efficient light emitters because a phonon with a high momentum is required to transfer an electron from the conduction to the valence band. In a recent study ...
Theoretical study about the relations among coefficients of stimulated emission, spontaneous emission and absorption in indirect bandgap semiconductor

Escalante Fernández, José María; Martínez Abietar, Alejandro José (Elsevier, 2013-02-15)

[EN] We show a theoretical study that permits us to obtain the relationship between the coefficients of stimulated emission, spontaneous emission and absorption in indirect bandgap semiconductors, including multiphoton and ...
