Golden spiral photonic crystal fiber: polarization and dispersion properties [PDF]
, 2008 A golden spiral photonic crystal fiber (GS-PCF) design is presented in which air holes are arranged in a spiral pattern governed by the golden ratio, where the design has been inspired by the optimal arrangement of seeds found in nature.

Phase-matching-induced near-chirp-free solitons in normal-dispersion fiber lasers
Light: Science & Applications, 2022 Direct generation of chirp-free solitons without external compression in normal-dispersion fiber lasers is a long-term challenge in ultrafast optics. We demonstrate near-chirp-free solitons with distinct spectral sidebands in normal-dispersion hybrid ...

Dynamics of Nonlinear Optics with Different Analytical Approaches
Fractal and Fractional, 2023 In this article, we investigate novel optical solitons solutions for the Lakshmanan–Porsezian–Daniel (LPD) equation, along with group velocity dispersion and spatio-temporal dispersion, via three altered analytical techniques.

Second-order achromat design based on FODO cell
Physical Review Special Topics. Accelerators and Beams, 2011 Two dipole doglegs are widely used to translate the beam axis horizontally or vertically. Quadrupoles are placed between the two consecutive dipoles to match first-order dispersion and provide betatron focusing.

Dispersion-managed soliton in optical fibers with zero average dispersion
, 2000 The dispersion-managed (DM) optical system with step-wise periodical variation of dispersion is studied in the framework of path-averaged Gabitov-Turitsyn equation. The soliton solution is obtained by iterating the path-averaged equation.
