On Pulse Duration, Bandwidth and Spectral Efficiency of Second and Third Order Soliton Pulses
01 June 2017
The limit of spectral efficiency is derived numerically for second and third order soliton pulses considering phase modulation of the spectral amplitudes. The optimum pulse to achieve the smallest time-bandwidth product is found by optimizing the eigenvalue locations and magnitudes of spectral amplitudes. This limit is approximated analytically by estimation of the pulse-duration and bandwidth of multi-solitons.
