Generalized view of Gaussian pulse-transmission characteristics in single-mode optical fibers

Compensation of soliton broadening in nonlinear optical fibers with loss

A novel optical fiber is proposed that supports the lowest-order soliton despite the presence of optical loss. Groupvelocity dispersion of this fiber decreases with distance, in accord with soliton attenuation that is due to the inherent optical loss of the fiber.

Propagation characteristics of frequency-chirped super-Gaussian optical pulses

It is demonstrated that the rms width of optical pulses propagating along an optical fiber varies parabolically with distance, irrespective of initial pulse form or frequency chirp. This result is used to analyze the propagation characteristics of super-Gaussian optical pulses with respect to pulse broadening, pulse compression, and information- carrying capability. Comparison with the corresponding properties for Gaussian pulses clearly shows the optimum character of the latter.
