Materials for High Temperature Spectral Hole Burning Optical Storage

Abstract

The optical properties of four Tm(3+) ion - organic ligand chelate complexes in a poly(methyl methacrylate) matrix were studied. These materials are interesting for potential applications of optical hole-burning frequency and time-domain storage and processing. Optical absorption, steady state and time-resolved photoluminescence, and spectral hole-burning at the transition between 3-H6 (1) and 3-H4 (1) crystal-field levels were studied at temperatures between 1.4 and 300 K. The heterodyne grating-generated scan interferometric technique has been demonstrated for the real time detection of the femtosecond data signal.
