Shaping Matter with Acoustic Waves: From Particles to Functional Structures

Advanced Functional Materials, EarlyView.
Acoustic‐directed assembly is reviewed as a materials‐oriented strategy for organizing particles, polymers, metals, and biological systems into functional structures. The review distinguishes reversible manipulation from permanent structure formation through medium fixation, particle fixation, and in situ material generation, highlighting routes toward

Ultra-broadband wavelength conversion based on four-wave mixing in a Raman DFB fiber laser

We report highly efficient four-wave mixing (FWM) within a 30cm-long centre pi phase-shifted Raman DFB fiber laser with a continuous frequency tuning range of ~19.9 THz with the FWM conversion efficiency up to ...

All‐Solution‐Processed HgTe Quantum Dot Photodetectors for Extended Short‐Wavelength Infrared Range Enhanced by Plasmonic ITO Nanocrystals

Advanced Functional Materials, EarlyView.
All‐solution‐processed, low‐cost extended short‐wavelength infrared photodetectors are realized by coupling colloidal HgTe quantum dots to plasmonic In2O3:Sn,F nanocrystals. Localized surface plasmon resonances boost and spectrally tailor light absorption between 1500 and 3000 nm, enabling responsivities above 40 A W−1.

Four-wave mixing in Weyl semimetals

, 2020
Weyl semimetals (WSMs) have unusual optical response originated from unique topological properties of their bulk and surface electron states. Their third-order optical nonlinearity is expected to be very strong, especially at long wavelengths, due to ...

An In Situ Oxidation Strategy for Ti3C2@TiO2 Heterojunction: Narrow‐Band Photodetection and Trace Chromium Ion Determination

Advanced Functional Materials, EarlyView.
A Ti3C2@TiO2 heterostructure has been successfully fabricated by an in situ oxidation approach. The as‐fabricated Ti3C2@TiO2‐based photodetector exhibits narrow‐spectrum response with excellent stability. It also realizes sensitive Cr(VI) detection in a large concentration range of 10−12–10−6 M with an ultra‐low detection limit of 7.6 × 10−12 M ...

A solid one-dimensional microstructured optical fiber with high nonlinearity and low dispersion at 1.55 microns

, 2009
We report on the fabrication of a solid one-dimensional microstructured fiber with high nonlinearity and low dispersion at 1.55µm. A four-wave-mixing based tunable wavelength-conversion scheme was experimentally demonstrated in just 1.5m of this ...
