We combine sub-cycle, mid-infrared spectroscopy and near-field microscopy to achieve a spatial resolution of 25 nm and a temporal resolution of 50 fs. Using our nano-FTIR technology we can spatially, temporally and spectrally resolve the femtosecond carrier-dynamics in solid state materials like photo excited InAs nanowires.
THz generation under the excitation by ultrashort optical pulses from ordered arrays of GaAs nanowires is reported. It was found that the efficiency of THz radiation generation increases due to the resonant leaky mode excitation in nanowires. The THz generation mechanisms have been identified. It is shown that the efficiency of the terahertz generation at optimum geometrical parameters of an array...
