Hi Vikas,
As Soliton based optical fiber communication systems are more suitable for long haul communication because of their very high information carrying capacity and repeater less transmission.Soliton pulses does not affected(by dispersion) after long distance communication.
The fact that solitons are spatially localized and propagate with (little to) no deformation makes them the carriers of choice for modern optical communication, as they can be used to encode a bit in a small amount of space through the presence or absence of the pulse in a designated temporal window.
We have a number of challenges still need to be overcome to arrive at spatially continuous, fine resolution, sensing and actuation, the time seems ripe for the investigation of advanced control techniques for active dispersion management related to Solitons.
we could develop an L1 adaptive control scheme for the problem of active dispersion management for propagation of solitons along uncertain fibers.
I want to share some links:
