Tunability of space-time wave packet carrying tunable and dynamically changing OAM value
Tobias Kippenberg, Maxim Karpov, Hao Song, Xinzhou Su
Space-time (ST) wave packets have gained much interest due to their dynamic optical properties. Such wave packets can be generated by synthesizing frequency comb lines, each having multiple complex-weighted spatial modes, to carry dynamically changing orbi ...
Optica Publishing Group2022Local Nondeterminism and Local Times of the Stochastic Wave Equation Driven by Fractional-Colored Noise
We investigate the existence and regularity of the local times of the solution to a linear system of stochastic wave equations driven by a Gaussian noise that is fractional in time and colored in space. Using Fourier analytic methods, we establish strong l ...
SPRINGER BIRKHAUSER2022Zero dispersion Kerr solitons in optical microresonators
Tobias Kippenberg, Junqiu Liu, Wenle Weng, Miles Henry Anderson, Alexey Tikan
Solitons are shape preserving waveforms that are ubiquitous across nonlinear dynamical systems from BEC to hydrodynamics, and fall into two separate classes: bright solitons existing in anomalous group velocity dispersion, and switching waves forming 'dark ...
NATURE PORTFOLIO2022How Lagrangian States Evolve Into Random Waves
In this paper, we consider a compact connected manifold (X, g) of negative curvature, and a family of semi-classical Lagrangian states f(h)(x) = a(x)e(i phi(x)/h) on X. For a wide family of phases phi, we show that f(h), when evolved by the semi-classical ...
ECOLE POLYTECHNIQUE2022Generation of OAM-carrying space-time wave packets with time-dependent beam radii using a coherent combination of multiple LG modes on multiple frequencies
Tobias Kippenberg, Maxim Karpov, Zhe Zhao, Hao Song, Xinzhou Su
Space-time (ST) wave packets, in which spatial and temporal characteristics are coupled, have gained attention due to their unique propagation characteristics, such as propagation invariance and tunable group velocity in addition to their potential ability ...
Optica Publishing Group2022Metasurface Near-Field Measurements with Incident Field Reconstruction Using a Single Horn Antenna
Shourya Dutta Gupta, Ville Tuovi Tiukuvaara
Metasurfaces (MSs) are the 2-D equivalent of metaterials, the latter being a class of artificial engineered materials exhibiting peculiar electromagnetic properties [1], [2]. Generally constructed as arrays of deeply sub-wavelength resonant particles on a ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2022Microresonator Dissipative Kerr Solitons Synchronized to an Optoelectronic Oscillator
Tobias Kippenberg, Wenle Weng, Jijun He
Using phase-modulation-induced potential gradient whose period is synchronized to a microwave opto-electronic oscillator, dissipative Kerr solitons generated in a crystalline optical microresonator are trapped by the soliton tweezing effect, exhibiting a s ...
AMER PHYSICAL SOC2022Local Emergence of Peregrine Solitons: Experiments and Theory
It has been shown analytically that Peregrine solitons emerge locally from a universal mechanism in the so-called semiclassical limit of the one-dimensional focusing nonlinear Schrodinger equation. Experimentally, this limit corresponds to the strongly non ...
FRONTIERS MEDIA SA2021Partial discharge localization using time reversal: application to power transformers and gas-insulated substations
Marcos Rubinstein, Mohammad Azadifar, Farhad Rachidi-Haeri, Amirhossein Mostajabi, Hamidreza Karami
A method for locating one or multiple partial discharge sources in a power transformer or a Gas-Insulated Substation, whereby the partial discharges emit electromagnetic and acoustic waves, the method comprising recording a signal corresponding to the wave ...
2021OASE 108. Ups & Downs. Reception Histories in Architecture
What is good, less good, or bad architecture? This issue of OASE examines how shifting appreciations, for very diverse reasons, can function as a productive misunderstanding, and as a lever to advance architectural criticism and pry thinking about architec ...
