Nested long period grating interferometers [PDF]

, 2007
The concept of nested fibre optic long period grating (LPG) based interferometers is introduced. A number of in-series, identical LPGs may be used to form a set of nested, multiplexed Mach-Zehnder interferometers that may demodulated and demultiplexed

Substrate stiffness regulates cell fate and its applications in the repair of motor system: From two dimensions to three dimensions

BMEMat, EarlyView.
Substrate stiffness with different dimensions (2D and 3D) exerts a regulatory role in cellular behaviors, thereby governing cell fate decisions. Biomaterials with tunable stiffness exhibit substantial functional potential for the repair and regeneration of the motor system.

Simultaneous generation of first- to fourth-order OAM modes based on a cascaded preset-twist long-period fiber grating

Nanophotonics
We propose and demonstrate the simulation and fabrication of an all-fiber orbital angular momentum (OAM) mode converter capable of generating first- to fourth-order modes simultaneously, which is realized by inscribing a cascaded preset-twist long-period

From Charge‐Transfer Adducts to (Tri)Halide‐Templated Supramolecular Cages: Covalent vs Ionic Products in the Reactions of Pyridin‐4‐ylthio‐Substituted Tetrathiafulvalene With Dihalogens and Interhalogens

Chemistry – A European Journal, EarlyView.
The reactions between tetra(pyridin‐4‐ylthio)tetrathiafulvalene and Br2/I2/ICl/IBr led to a variety of products, including a rare example of neutral 1:4 CT adduct and ionic products showing supramolecular cage motifs at (tri)halide templates. The nature of the reaction products was elucidated based on XRD analysis, Raman spectroscopy and QTAIM, NCI ...

Phase encoding and decoding of short pulses at 10Gb/s using superstructured fiber Bragg gratings [PDF]

, 2001
A 7-chip, 160-Gchip/s phase-shift keyed code is assigned to short pulses after reflection from a superstructured fiber Bragg grating. The code is then recognized by a second grating, which is nominally identical to the encoder grating.

Finalisation of the European Approach to Assess the Fire Performance of Facades—Brief Information on the Outcome of the Project

Fire and Materials, EarlyView.
ABSTRACT This research was conducted within the framework of project SI2.825082, funded by the European Commission—DG GROW. The project's objective was to finalise a European approach for assessing the fire performance of façades under medium and large fire exposure conditions.

Rapidly reconfigurable optical phase encoder-decoders based on fiber Bragg gratings [PDF]

, 2006
We demonstrate the capacity for fast dynamic reconfiguration of optical code-division multiple access (OCDMA) phase en/decoders based on fiber Bragg gratings and a thermal phase-tuning technique.
