Abstract :
Summary form only given. Coherent transient optical memories and signal processors (CTOMs and CTOPs) take advantage of an inhomogeneously broadened absorber (IBA) to store and process temporal waveforms with data bandwidths exceeding 10 GHz and with extermely high storage and processing densities. In this paper, we propose and demonstrate techniques to compensate for the deleterious effects of dephasing in CTOMs and CTOPs. Compensation is achieved by applying an intensity ramp, which matches the inverse of the decay while maintaining roughly the same pulse area in the pattern stream to be recorded. We used the 783-nm transition of Tm/sup 3+/:YAG (0.1 at.%) at cryogenic temperatures to demonstrate the compensation techniques.
