Bit selective erasure of photon-echo data using Ti : S and dye laser systems: a comparative analysis

Mohan, R. K ; Elman, U and Kröll, Stefan LU (1998) In Optics Communications 158(1-6). p.149-158
Abstract
It is investigated how the erasure efficiency for a single bit of data, stored using photon echoes, depends on the data writing time and data storage time. A comparative analysis of the erasure efficiency using a Ti:S laser system and a ring dye laser system is performed. The results clearly establish that the Ti:S laser system, which has a narrower line width than the dye laser system, could be used for efficient erasure over a much larger range of data writing and data storage times. A simple threshold detection-based scheme to convert the photon-echo signals into bits is also used to compare the performances of the two laser systems. A surprising but encouraging result was that it may not be absolutely necessary to have a very high... (More)
