Chromatic Dispersion Diagnosis of Three OAM States in 5.58 Kilometer Ring-Core Fiber Link
IEEE Photonics Journal, 2017 We present the investigation on chromatic dispersion characteristics of three orbital angular momentum (OAM) states in 5.58 km ring-core fiber (RCF) link. Steady transmissions of different OAM mode orders spanning from −2 to +2 via the 5.58&

Phase-matching-induced near-chirp-free solitons in normal-dispersion fiber lasers
Light: Science & Applications, 2022 The fiber birefringence, chromatic dispersion, and nonlinear effect follow a phase-matching principle, enabling the formation of birefringence-managed solitons in normal-dispersion fiber lasers containing a section of polarization-maintaining fiber.

The characterization of step index single mode silica fiber for long haul signal communication
Materials Research, 2005 The optical properties of single mode fibers, which are drawn from the silica preform made by MCVD technique, have been studied. The properties such as cutoff wavelength, chromatic dispersion, and polarization mode dispersion (PMD) were studied for 2.3 ...

Theory of the Chromatic Dispersion, Revisited
Arxiv.org Repository, 2020 We derive general analytic expressions for the chromatic dispersion orders valid to infinity, due to the k vector or phase {\phi} dependence on the wavelength. Additionally, we identify polynomials and recursion relations associated with the chromatic dispersion orders and draw analogy to the generalized Lah and Laguerre transformations.

Meta-Dispersive 3D Chromatic Confocal Measurement. [PDF]
Adv Sci (Weinh)Abstract 3D reconstruction can perceive the detailed structures of real‐world objects. Integrating metasurfaces with stereo vision or structured‐light projection enables compact and efficient 3D reconstruction systems, beneficial for next‐generation sensing, augmented reality, and biomedical applications. Nevertheless, the limitations
