A fully stabilized scheme for dispersion management

Summary form only given. The use of the dispersion management (DM) for improving the soliton-based mode of data transmission in nonlinear optical fibers has recently attracted a great deal of attention. While DM helps to suppress a number of negative effects in the soliton-transmission mode e.g. the Gordon-Haus jitter, sufficient suppression of the soliton´s jitter and interactions (both inside each channel and between the channels, in the case of the WDM regime) is not possible without guiding filters. Therefore, considerable effort has been made to theoretically study a joint effect of DM and filters on the soliton propagation. Although the combination of DM with the filters may produce quite good results, it does not resolve all the problems. In particular, in a lumped model, which treats the periodically inserted filters as discrete objects, an instability is possible if the amplification-filtering and DM periods coincide, and the location of the filters inside a DM cell is chosen in a wrong way. We propose a model that provides for fully stable propagation of the DM solitons. The stabilizing element is an additional lossy core, which is linearly coupled to the main soliton-bearing one.
