“…The temporally shorter the pulse, the larger the distortions. Moreover, while the dispersion effects are proportional to the medium's length, it is inversely proportional to the square of the pulse's temporal width; therefore, ultra-short pulses are prone to being affected by dispersion even in relatively short media [8][9][10].…”

Ultrashort pulses are severely distorted even by low dispersive media. While the mathematical analysis of dispersion is well known, the technical literature focuses on pulses, Gaussian and Airy pulses, which keep their shape. However, the cases where the shape of the pulse is unaffected by dispersion is the exception rather than the norm. It is the objective of this paper to present a variety of pulse profiles, which have analytical expressions but can simulate real-physical pulses with great accuracy. In particular, the dynamics of smooth rectangular pulses, physical Nyquist-Sinc pulses, and slowly rising but sharply decaying ones (and vice versa) are presented. Besides the usage of this paper as a handbook of analytical expressions for pulse propagations in a dispersive medium, there are several new findings. The main findings are the analytical expressions for the propagation of chirped rectangular pulses, which converge to extremely short pulses; an analytical approximation for the propagation of super-Gaussian pulses; the propagation of the Nyquist-Sinc Pulse with smooth spectral boundaries; and an analytical expression for a physical realization of an attenuation compensating Airy pulse.

“…Transmission‐type SWCNT‐polymer composite films are typically chosen for use in fiber lasers as they are compact, inexpensive, and easy to fabricate. Nevertheless, the performance of mode‐locked lasers is still subjected to the amount of dispersion present within the laser structure, which takes into account contributions not only from the gain medium but also from fiber connectors of the other components . This task becomes more difficult as manufacturers rarely include dispersion value in EDF and optical components data sheets.…”

We have numerically studied passive mode locking in figure of eight laser containing microstructured optical fiber. We demonstrate for the first time to the best of our knowledge the generation of bound states in such configuration in the normal dispersion regime. The numerical simulations are based on extended nonlinear Schrödinger equation using the symmetrized split-step Fourier method. The numerical results show that single pulse or bound solitons can be obtained when the parameters of the cavity are suitably chosen. We identify the small signal gain and the microstructured optical fiber's nonlinear coefficient as key parameters for the generation of bound solitons in figure of eight fiber laser.
