Microring Resonator Dispersion Metrology With Neural Networks

open access: yesNanophotonics, 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.

Analytic multi-soliton solutions of the generalized Burgers equation [PDF]

open access: yes, 2011
The most elementary ansatz of the double-Exp-function method for finding exact double-wave solutions can be produced by an extension of a two-soliton ansatz in a fractional form.

Seven‐Fold Compression of Mid‐Infrared Pulses Using a Series of Titanium Dioxide Plates

open access: yesAdvanced Optical Materials, Volume 14, Issue 35, 18 September 2026.
Here, a sequence of three titanium dioxide plates is used to compress a mid‐infrared pulse from 103.9 femtoseconds to 14.1 femtoseconds (about two optical cycles) without the use of external dispersion compensation. The approach maintains high efficiency and produces pulses with a stable carrier‐envelope phase, providing a compact platform for ...

Thin‐film lithium niobate photonics: Frontiers in millimeter‐wave and terahertz generation and integrated applications

open access: yesInfoScience, Volume 3, Issue 3, September 2026.
With the advancement of 6G communications, high‐precision radar, and advanced imaging technologies, there is a growing demand for compact, high‐performance light sources capable of generating high‐frequency radio waves (millimeter‐wave and terahertz waves). This article systematically introduces how to efficiently generate these high‐frequency waves on

Solitons on lattices and curved space-time [PDF]

open access: yes, 2001
This thesis is concerned with solitons (solutions of certain nonlinear partial differential equations) in certain cases when the underlying space is either a lattice or curved. Chapter 2 of the thesis is concerned with the outcome of collisions between a

S(3) skyrmions and the rational map ansatz [PDF]

open access: yes, 2000
This paper discusses multi-skyrmions on the 3-sphere with variable radius L using the rational map ansatz. For baryon number B = 3,...,9 this ansatz produces the lowest energy solutions known so far.
