This paper presents the vision shared by partners from the CELTIC project HOMESNET about Femto Base Station deployed at Home, i.e. Home Base Station.

Femtocells, despite their name, pose a potentially large disruption to the carefully planned cellular networks that now connect a majority of the planet's citizens to the Internet and with each oth

The transient current response of bulk GaAs and InP is investigated at ultrahigh electric fields.

By pumping a fiber in the anomalous group velocity dispersion regime with a color center laser, we generate a femtosecond distributed soliton spectrum with tau >~100fsec covering a wide spectral

High-sensitivity, femtosecond differential transmission measurements on self-organized InAs quantum dots at room temperature allow us to determine the dynamics of resonantly excited electron-hole p

We use tunable optical pulses of 150 fs duration to measure the dynamics of exciton absorption in optically excited room temperature GaAs/AlGaAs multiple quantum well structures.

We report the first direct measurement of the relative bleaching strength of excitonic absorption by "cool" free e-h pairs and cold excitons.

We report the first observation of non-thermal photoexcited carrier distributions in GaAs quantum well structures at room temperature.

A study of nonequilibrium transport of carriers in GaAs and InP at electric fields up to 130 kV/cm and with a temporal resolution of 20 fs is presented.
