Demonstration of optically modulated dispersion forces

open access: yesOptics Express, 2007
We report the first experiment on the optical modulation of dispersion forces through a change of the carrier density in a Si membrane. For this purpose a high-vacuum based atomic force microscope and excitation light pulses from an Ar laser are used ...

Consequences of non-differentiable angular dispersion in optics: tilted pulse fronts versus space-time wave packets. [PDF]

open access: yesOptics Express, 2021
Conventional diffractive and dispersive devices introduce angular dispersion (AD) into pulsed optical fields, thus producing so-called 'tilted pulse fronts'. Naturally, it is always assumed that the functional form of the wavelength-dependent propagation

Asymptotic dispersion engineering for ultra-broadband meta-optics

open access: yesNature Communications, 2023
Dispersion decomposes compound light into its monochromatic components, which is detrimental to broadband imaging but advantageous for spectroscopic applications.

Phase-dispersion optical tomography [PDF]

open access: yesOptics Letters, 2001
We report on phase-dispersion optical tomography, a new imaging technique based on phase measurements using low-coherence interferometry. The technique simultaneously probes the target with fundamental and second-harmonic light and interferometrically measures the relative phase shift of the backscattered light fields.

Physics‐Informed Neural Network for Nonlinear Dynamics in Fiber Optics [PDF]

open access: yesLaser & Photonics Reviews, 2021
A physics‐informed neural network (PINN) that combines deep learning with physics is studied to solve the nonlinear Schrödinger equation for learning nonlinear dynamics in fiber optics.

Detecting Water in the Atmosphere of HR 8799 c with L-band High-dispersion Spectroscopy Aided by Adaptive Optics [PDF]

open access: yesAstronomical Journal, 2018
High-dispersion spectroscopy of brown dwarfs and exoplanets enables exciting science cases, e.g., mapping surface inhomogeneity and measuring spin rate. Here, we present L-band observations of HR 8799 c using Keck NIRSPEC (R = 15,000) in adaptive optics (

Controlling the sign of chromatic dispersion in diffractive optics [PDF]

open access: yes, 2017
Diffraction gratings disperse light in a rainbow of colors with the opposite order than refractive prisms, a phenomenon known as negative dispersion [1, 2].

Dispersion-less Kerr solitons in spectrally confined optical cavities [PDF]

open access: yesLight: Science & Applications, 2021
Solitons are self-reinforcing localized wave packets that manifest in the major areas of nonlinear science, from optics to biology and Bose–Einstein condensates.
