Persistent 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...
متن کاملOrigin of persistent hole burning of N - V centers in diamond
New satellite features and antiholes in the persistent hole-burning spectrum of N-V centers in diamond, as well as their dependences on applied electric fields and frequency within the inhomogeneous absorption line, are reported. These results, together with reassignments of spin states of this center, permit an understanding of the origin of the satellite holes as well as of possible mechanism...
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 کاملSpectroscopy , persistent hole burning , and holographic applications of naphtophthalocyanine / haloanthracene systems
We report on the spectroscopic and hole burning properties of free-base naphtophthalocyanine with and without 1chloranthracene in polymer host. These materials exhibit a strong 0–0 absorption band in the region 800 nm matching the wavelength range of most semiconductor and Ti:Sapphire lasers. The materials studied feature two persistent hole burning photochemical mechanisms, i.e. one-photon pro...
متن کاملSpectral hole burning in naphthalocyanines derivatives in the region 800 nm for holographic storage applications
Persistent spectral hole burning is studied for several free-based and metallo-naphthalocyanine derivatives in polymer hosts. These materials exhibit a strong 0}0 absorption band in the region 800 nm matching the wavelength range of most semiconductor diode lasers and Ti : Sapphire lasers. Metallo-naphthalocyanines demonstrate a nonphotochemical hole-burning mechanism that is likely related to ...
