Abstract
We propose and experimentally demonstrate a technique that compensates for the deleterious effects of homogeneous dephasing on the output signal of coherent transient optical memories and processors. In coherent transient memories without compensation, storage of information pattern streams with durations on the order of the homogeneous transverse dephasing time, T 2, experiences significant distortions due to exponential decay. By appropriately tailoring the intensity of the input pattern information stream, we show such a pattern stream can be recalled with relatively uniform power in each bit. In processors without compensation, we show that patterns of duration ∼ T 2 can cause distortions in the emitted correlation output, and that compensation can remove this distortion. Our experimental demonstrations of extending the practicable duration of pattern pulses represent roughly an order of magnitude improvement in (a) the storage density of coherent transient optical memories, and (b) the time-bandwidth product of coherent transient optical processors.
