Breakup of a below-resonance femtosecond pulse is observed in a room-temperature GaAs/AlGaAs multiple-quantum-well waveguide using cross-correlation techniques. The breakup is due to neither self-induced transparency nor temporal solitons. Instead, c

We report the observation of a polarization-dependent spectral hole burned in the Q-band absorption peak of a nearly amorphous fluoro—aluminum phthalocyanine thin film by 130 fs optical pulses at room temperature. The hole is spectrally coincident

The room‐temperature nonlinear absorption spectra of a 40 A GaInAs/AlInAs and a 90 A GaAlInAs/AlInAs multiple quantum well (MQW) were measured near 1.3 μm using a pump and probe technique. Saturation carrier densities at the heavy‐hole exciton p

On observe aussi cet effet dans un coupleur directionnel non lineaire quand une transmission totale augmente les guides d'onde. Les equations de Bloch des semiconducteurs du systeme sont resolues numeriquement. La saturation d'absorption transitoire

Side polished fibers (SPF) are interesting devices because they represent a method of altering a light wave's amplitude or phase as it travels in an optical fiber. This eliminates many of the practical problems associated with fiber-optic devices mad
