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 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 ...
