Extracting Group Velocity Dispersion values using quantum-mimic Optical Coherence Tomography and Machine Learning. [PDF]
Sci Rep, 2023 Quantum-mimic Optical Coherence Tomography (Qm-OCT) images are cluttered with artefacts - parasitic peaks which emerge as a by-product of the algorithm used in this method.

Quasi-linear analysis of dispersion relation preservation for nonlinear schemes
Advances in Aerodynamics, 2022 In numerical simulations of complex flows with discontinuities, it is necessary to use nonlinear schemes. The spectrum of the scheme used has a significant impact on the resolution and stability of the computation.

Dispersion engineering of W2 steeple-house-defect waveguide photonic crystal
Results in Physics, 2020 An epitome for dispersion and buffering in a photonic crystal was set forth. Slots in the form of a line of contacted steeple-houses are implanted in a two-line photonic crystal waveguide (2LPCW) to form an irregular slot of steeple-house defect PCW ...

Comments about dispersion of light waves
Journal of the European Optical Society-Rapid Publications, 2022 Dispersion of light waves is well known, but the subject deserves some comments. Certain classical equations do not fully respect causality; as an example, group velocity vg is usually given as the first derivative of the angular frequency ω with respect

Dispersion Engineering of Silicon Nitride Microresonators via Reconstructable SU-8 Polymer Cladding
Micromachines, 2022 In this work, we propose a novel way to flexibly engineer the waveguide dispersion by patterning the cladding of waveguide microresonators. Experimentally, we demonstrate silicon nitride waveguides with air-, oxide-, and SU-8 polymer-cladding layers and ...
