Wavelength and duration tunable 10 GHz 1.3ps pulse source using dispersion decreasing fiber based distributed Raman amplification [PDF]
, 2004 We experimentally demonstrate a novel pulse compression scheme using dispersion decreasing fiber (DDF) based distributed Raman amplification. We adiabatically compress 10GHz, 13ps seed pulses generated using a commercially available electro-absorption ...

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Hot‐wet extremes (HWEs) are intensifying in the Beijing–Tianjin–Hebei region, but their fine‐scale diurnal urban–rural contrasts remain unclear. Using summer observations from 1,962 automatic weather stations during 2016–2024, we identify threshold‐exceeding HWE days and show that urban areas experience more compound day–night and independent ...

Soliton-pair dynamical transition in mode-locked lasers
, 2021 Multi-soliton mode-locked laser waveforms are much sought as a complex light source for research and applications, but are difficult to manipulate effectively because of the elaborate and diverse interactions present.

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract Satellite observations during ionospheric modification experiments have reported trans‐ionospheric high‐frequency (HF) wave propagation even when the pump frequency lies below the peak plasma frequency. Such behavior is often attributed to large‐scale density irregularities that locally permit ordinary‐mode (O‐mode) propagation, but this does ...

Dimensional Synthesis for Emulating Nonlinear Disclination Dynamics
Nanophotonics, Volume 15, Issue 17, 11 September 2026.(a) Intensity distributions of the 2D disclination lattice under corner‐site excitation in the linear (a1), weakly nonlinear (a2), and strongly nonlinear (a3) regimes. (b) Corresponding one‐dimensional synthesized lattices (1DSLs) obtained through Lanczos mapping under the same nonlinear regimes.

Optical linewidth of soliton microcombs
, 2022 Soliton microcombs provide a versatile platform for realizing fundamental studies and technological applications. To be utilized as frequency rulers for precision metrology, soliton microcombs must display broadband phase coherence, a parameter ...

A New Family of Buckled Rings on the Unit Sphere
MathematicsBuckled rings, also known as pressurized elastic circles, can be described as critical points for a variational problem, namely the integral of a quadratic polynomial in the geodesic curvature of a curve. Thus, they are a generalization of elastic curves,

Microring Resonator Dispersion Metrology With Neural Networks
Nanophotonics, Volume 15, Issue 17, 11 September 2026.We present a machine learning framework for inverse and forward characterization of microring resonators, inferring geometry and material dispersion from sparse spectral data. The approach achieves nanometer‐scale accuracy and > 99% material identification, while reconstructing full dispersion spectra.

Soliton and breather splitting on star graphs from tricrystal Josephson junctions [PDF]
, 2019 We consider the interactions of traveling localized wave solutions with a vertex in a star graph domain that describes multiple Josephson junctions with a common/branch point (i.e., tricrystal junctions). The system is modeled by the sine-Gordon equation.
