Ultrafast optical nonlinearity of low-temperature-grown GaInAs/AlInAs quantum wells at a wavelength of 1.55 m
Abstract
The ultrafast optical nonlinearity of low-temperature-grown GaInAs/AlInAs quantum wells at a wavelength of 1.55 m was discussed. The nonlinear transmission was studied at room temperature in pump-probe experiments with 140-fs pulses at a center wavelength of 1.55 m from a mode-locked Er:fiber laser. It was shown that Be-doped low temperature GaInAs/AlInAs multi quantum wells are promising materials for Tbit/s all-optical switching devices.
