Review of long period fiber gratings written by CO₂ laser [PDF]

, 2010
This paper presents a systematic review of long period fiber gratings (LPFGs) written by the CO2 laser irradiation technique. First, various fabrication techniques based on CO2 laser irradiations are demonstrated to write LPFGs in different types of ...

Study of single mode tapered fiber-optic interferometer of different waist diameters and its application as a temperature sensor [PDF]

Journal of the European Optical Society-Rapid Publications, 2014
We have proposed a study on single-mode tapered optical fiber for temperature sensing application. A theoretical analysis and its experimental validation were carried out to study the taper profile for highly sensitive temperature sensor.

Artery‐on‐Chip Demonstrates Mechanical and Functional Features of Healthy and Diseased Living Smooth Muscle Tissue

Advanced Functional Materials, EarlyView.
This article details the development of an artery‐on‐chip platform for in vitro arterial disease modeling and therapeutic discovery. It describes the fabrication of a fibrin biomaterial scaffold seeded with iPSC‐derived smooth muscle and endothelial cells, mimicking native artery properties. Two genetic disease models showcase the platform's ability to

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

RGB generation by four-wave mixing in small-core holey fibers [PDF]

, 2007
We report the generation of white light comprising red, green, and blue spectral bands from a frequency-doubled fiber laser by an efficient four-wave mixing process in submicron-sized cores of microstructured holey fibers.

Octagonal toroid microcavity for mechanically robust optical coupling

AIP Advances, 2015
Light is usually coupled to a whispering gallery mode cavity using a tapered fiber. However, it is difficult to stabilize the optical coupling against mechanical vibration because it requires sub-μm control of the gap distance between the fiber and ...

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.

Microscopic Origin of Temperature‐Dependent Anisotropic Heat Transport in Ultrawide‐Bandgap Rutile GeO2

Advanced Functional Materials, EarlyView.
Rutile GeO2${\rm GeO}_{2}$ exhibits orientation‐dependent heat transport with temperature‐dependent anisotropy, showing higher cross‐plane thermal conductivity along [001] than along the equivalent in‐plane [100] and [010] directions. Temperature‐dependent TDTR measurements and first‐principles phonon calculations identify the microscopic phonon ...
