Many aspects of the protein dynamics involved in ligand binding to heme proteins remain poorly understood.
Optical logic is discussed here which is based on integrated optical wiring much like today's integrated circuits, except with possible operation down to subpicosecond times.
Laser studies on intramolecular hydrogen atom (H) transfer in organics have led to an important insight into the mechanism of ultrafast H transfer reactions.
We report measurements of luminescence spectra of InGaAsP with 10 psec time resolution and a wide dynamic range. The spectra are dominated by band-to-band recombination processes.
Wavelength shifts caused by chirp in pulses generated from a gain-switched InGaAsP distributed-feedback laser have been measured with 0.5 ps resolution.
We report ultrafast all-optical switching between two orthogonal linear polarizations in a periodically twisted, birefringent fiber filter.
Preliminary experiments utilizing thin polycrystalline OMVPE GaAs/Si sup O sub 2 films, has resulted in photoconductive detectors with sampling oscilloscope limited responses of 35 psec (FWHM), pho
We present a novel method of creating phonon excitations in a thin film of a chalcogenide glass.
An investigation of the dependence of the photoconductive lifetime and dark resistivity on ion mass, bombarding dose and substrate temperature is presented for ion implanted Fe-doped InP.
Measurements and theoretical calculations are presented for the photorefractive effect in three semi-insulating semiconductors (GaAs:EL2, InP:Fe and CdTe:V) using 29-ps pulses at a wavelength of 1.
