Regular perturbation on the group-velocity dispersion parameter for nonlinear fibre-optical communications [PDF]
Nat Commun, 2020 Communication using the optical fibre channel can be challenging due to nonlinear effects that arise in the optical propagation. These effects represent physical processes that originate from light propagation in optical fibres.

Group-velocity-dispersion engineering of tantala integrated photonics. [PDF]
Optics Letters, 2020 Designing integrated photonics, especially to leverage Kerr-nonlinear optics, requires accurate and precise knowledge of the refractive index across the visible to infrared spectral ranges.

Realizing normal group-velocity dispersion in free space via angular dispersion. [PDF]
Optics Letters, 2021 It has long been thought that normal group-velocity dispersion (GVD) cannot be produced in free space via angular dispersion. Indeed, conventional diffractive or dispersive components such as gratings or prisms produce only anomalous GVD. We identify the

Results in Physics, 2021 This work investigates the nonlinear Schrodinger equation (NLSE) with group velocity dispersion and second order spatiotemporal dispersion coefficients. The governing model is reduced into the classical nonlinear ordinary differential equation.

Strong group-velocity dispersion compensation with phase-engineered sheet metamaterials [PDF]
, 2014 Resonant metamaterials usually exhibit substantial dispersion, which is considered a shortcoming for many applications. Here we take advantage of the ability to tailor the dispersive response of a metamaterial, introducing a new method of group-velocity ...

Canceling and Inverting Normal and Anomalous Group‐Velocity Dispersion Using Space‐Time Wave Packets [PDF]
Laser & Photonics Reviews, 2022 Angular dispersion can counterbalance normal group‐velocity dispersion (GVD) that increases the wave‐vector length in a dispersive medium. By tilting the wave vector, angular dispersion reduces the axial wave number in this case to match the pre‐GVD ...

Numerical study of solitonic pulse generation in the self-injection locking regime at normal and anomalous group velocity dispersion. [PDF]
Optics Express, 2020 We developed an original model describing the process of the frequency comb generation in the self-injection locking regime and performed numerical simulation of this process.

Generation and dynamics of solitonic pulses due to pump amplitude modulation at normal group-velocity dispersion [PDF]
Physical Review A, 2019 We studied generation and dynamics of solitonic pulses, platicons, at normal group velocity dispersion due to the pump amplitude modulation. We proposed, that if the required frequency of amplitude modulation is too large for available modulators, it is ...

A unified model for age-velocity dispersion relations in Local Group galaxies: Disentangling ISM turbulence and latent dynamical heating [PDF]
, 2017 We analyse age–velocity dispersion relations (AVRs) from kinematics of individual stars in eight Local Group galaxies ranging in mass from Carina (M* ∼ 106 M⊙) to M31 (M* ∼ 1011 M⊙).

Self-focusing and group-velocity dispersion of pulsed laser beams in the inhomogeneous atmosphere.
Optics Express, 2018 We study self-focusing and group-velocity dispersion (GVD) effects in the inhomogeneous atmosphere on pulsed-laser space debris removal facilitated by a ground-based laser.
