Gain dynamics and ultrafast spectral hole burning in In„Ga...As self-organized quantum dots
Using a femtosecond three-pulse pump-probe technique, we investigated spectral hole-burning and gain recovery dynamics in self-organized In~Ga!As quantum dots. The spectral hole dynamics are qualitatively different from those observed in quantum wells, and allow us to distinguish unambiguously the gain recovery due to intradot relaxation and that due to carrier capture. The gain recovery due to...
متن کاملPersistent spectral hole burning by simultaneous two-photon absorption
We show for the ®rst time persistent spectral hole burning by simultaneous absorption of two 1138 nm photons in an inhomogeneously broadened S1 S0 Qy transition of unstable photo-tautomer of chlorin in polymer ®lm at low temperature. Spectrally selective hole burning is achieved due to high (10%) quantum eciency of photo-transformation in that system and high peak intensity (tens of GW/cm) o...

متن کاملPersistent spectral hole burning in an organic material for temporal pattern recognition
A broad-bandwidth persistent spectral hole-burning organic material is used as a fast optical processor that compares an input temporal-frequency profile with a recorded reference spectral shape. This patternrecognition procedure relies on a subpicosecond temporal cross-correlation process. The size of the phaseencoding spectral interval exceeds 1 THz. The storage material, the spectral encoder...
