Photoluminescence was used to study multiphoton excitations in porous Si. With picosecond exciting pulses in the mid-infrared, even a nine-photon excitation process could be readily observed. Excitations are likely of the multi-resonant, multi-step t

Transport Regulations rely essentially on the packaging and do not take into account the contribution to safety which may be made by other features of the operation. In some situations, mainly for routine transports not fully complying with the Regul

We report on direct evidence of ultrafast carrier dynamics displaying features on the picosecond time scale in microcrystalline silicon (μc-Si:H). The dynamics of photogenerated carriers is studied by using above-band-gap optical excitation and prob

Using a mixed type-I/type-II GaAs/AlAs multiple-quantum-well sample, we have demonstrated an optically controllable and tunable terahertz (THz) filter. Long-lived electron–hole pairs in the quantum wells allow for efficient THz attenuation over a l

UV photoluminescence ~PL! from GaN thin films was observed by multiphoton excitation. The two-photon PL excitation spectrum near the band gap agrees with the theoretical two-photon-absorption spectrum. The pump-intensity dependence and the PL excitat

With the development of fast and efficient THz imaging using THz-time domain spectroscopy (THz-TDS), it has become possible to image biological samples in this frequency range. Such imaging studies are complementary to studies in other parts of the e

We have demonstrated a low power, optically-controllable, THz attenuator capable of high contrast ratios using a mixed type-I/type-II quantum well sample. When high free-carrier densities are optically excited in the quantum wells by a cw-laser, the
