Nearly 100 Nm Bandwidth Of Flat Gain With A Double-pumped Fiber Optic Parametric Amplifier [PDF]
, 2015 We demonstrate double-pumped fiber-optical parametric amplifiers with flat and broadband gain spectrum. Using specially fabricated highly non-linear fibers having low variations of the zero-dispersion wavelength and low PMD we obtain flat gain (23.5±1dB)

Validation of Taylor’s Frozen Hypothesis for DAS-Based Flow
SensorsAccurate measurement of pipeline flow is of great significance for industrial and environmental monitoring. Traditional intrusive methods have the disadvantages of high cost and damage to pipeline structure, while non-intrusive techniques can circumvent ...

Advanced Functional Materials, EarlyView.Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films
Advanced Functional Materials, EarlyView.Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...
