Optical gain by simultaneous photon and phonon confinement in indirect bandgap semiconductor acousto-optical cavities

Escalante Fernández, José María; Martínez Abietar, Alejandro José (Springer-Verlag, 2013)

[EN] Optical gain that could ultimately lead to light emission from silicon is a goal that has been pursued for a long time by the scientific community. The reason is that a silicon laser would allow for the development ...
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 of light and sound interaction in phoxonic crystal structures

Escalante Fernández, José María (Universitat Politècnica de València, 2013-11-19)

En esta tesis se realiza un estudio teórico de la interacción luz-sonido en estructuras foxonicas, con las cuales es posible el control de la luz y el sonido a la misma vez. Esta interacción en dichas estructuras se ...
