Adaptive control methods for ultrafast pulse propagation in opticalfibers

摘要

Adaptive control in combination with ultrafast pulse shapingnprovides a compelling approach to harness events that occur on thenfastest timescale available. This paper illustrates the application ofnadaptive pulse shaping to femtosecond pulse propagation at Λ=1550nnm in single-mode optical fibers. The approach is illustrated first bynthrough a numerical simulation of the technique. An experimentalndemonstration is described. The propagation of ~200-fs pulses isnsuccessfully achieved in the nonlinear regime by suitably preshaping theninput pulse using an adaptive feedback loop
