Toward Fully Soft and Multifunctional Shape Sensing via Optical Waveguide Arrays

Advanced Intelligent Systems, EarlyView.
This work develops a sheet made with arrays of soft optical fibers that can reconstruct its 3D surface shape. Synergy of the waveguides’ responses to bending and pressing force allows shape reconstruction with resilience to damage. Applied onto surfaces of robotic or living systems, our design can be implemented in virtual reality, teleoperation ...

High-power supercontinuum generation with picosecond pulses [PDF]

, 2010
We investigate both theoretically and experimentally the properties of supercontinuum generation in the nearinfrared and visible regimes using high-power picosecond pulses propagating in a photonic crystal optical fiber. We discuss the effect of the pump

Theory of Stimulated Brillouin Scattering in Fibers for Highly Multimode Excitations

Physical Review X
Stimulated Brillouin scattering (SBS) is often an unwanted loss mechanism in both active and passive fibers. Highly multimode excitation of fibers has been proposed as a novel route toward efficient SBS suppression.

Functional Polymer‐Engineered Magnetic Nanoparticles as Dual‐Modal Theragnostic Probes for Early Alzheimer's Disease Detection and Therapy

Advanced NanoBiomed Research, EarlyView.
The nanoparticle consists of a 3 nm iron oxide core functionalized with an amphiphilic polymer coating containing Aβ‐targeting DSA moieties and biocompatible PEG chains. This design supports measurable transport in a BBB‐related model and specific interaction with Aβ species, while providing MRI contrast enhancement for diagnosis and therapeutic ...

Spatio-temporal reshaping in multimode fibers [PDF]

, 2020
Multimode fibers received recently a renewed interest because of the ability to control the multimode propagation and to select, at the output, a quasi-single mode supporting the main part of the energy.

High-power cladding-pumped Raman and erbium-ytterbium doped fibre sources

, 2007
Raman fibres and rare-earth doped silica fibres have been investigated for many years as gain media for the amplification of optical signals in telecommunications thanks to their broad gain bandwidth. They are now widely used for that application.

Biomimetic Nanofiber Scaffold Coated With Acellular Matrices for Uterine Myometrial Tissue Engineering

Advanced NanoBiomed Research, EarlyView.
Schematic representation of acellular matrix generation from human uterine fibroblast cells, coating on polycaprolactone electrospun nanofibers, and subsequent in vitro and in vivo characterization. A tissue‐engineered scaffold tailored for uterine myometrium‐specific regeneration is designed. The electrospinning technique was used to fabricate aligned

Talbot interference of whispering gallery modes

APL Photonics
The Talbot self-imaging phenomenon is a fundamental interference effect that is natural to all waves with a periodic structure. We theoretically and experimentally study the Talbot effect for optical waves in the transverse angular domain using ...

Accelerating Nonlinear Interactions In Tapered Multimode Fibers

, 2018
We theoretically and experimentally demonstrate that the processes of multimode soliton fission and dispersive wave generation in parabolic-index multimode fibers, are substantially altered when the rate of intermodal nonlinear interactions is ...
