Simultaneous, independent measurement of temperature and strain using a tilted fibre Bragg grating [PDF]
, 2007 A single fibre Bragg grating is used to discriminate between temperature and strain by exploiting the core-cladding mode coupling of a tilted fibre Bragg grating (TFBG).

Advanced Functional Materials, EarlyView.Multianalyte, real‐time monitoring of bioprinted scaffolds remains challenging. Phosphorescence‐lifetime–based, optically responsive microparticles are embedded in diverse printable hydrogels (κ‐carrageenan, GelMA, PEGDA) to form biomaterial inks that report oxygen, glucose, lactate, and temperature.

Investigation on Strong Coupling Behaviors of THz Subwavelength Directional Couplers
IEEE Photonics Journal, 2012 To achieve strong coupling, conventional fiber-based directional couplers often require complicated fabrication. Here, by placing two identical THz subwavelength fibers parallel to each other and by simply tuning the separation in between, we investigate

A compact two-dimensional grating coupler used as a polarization splitter
, 2003 We demonstrate a novel polarization splitter based on a two-dimensional grating etched in a silicon-on-insulator waveguide. The device couples orthogonal modes from a single-mode optical fiber into identical modes of two planar ridge waveguides.

Advanced Functional Materials, EarlyView.We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,

Random mode coupling assists Kerr beam self-cleaning in a graded-index multimode optical fiber [PDF]
, 2019 In this paper, we numerically investigate the process of beam self-cleaning in a graded-index multimode optical fiber, by using the coupled-mode model.

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.

Fiber Bragg gratings in active multimode XLMA fibers for high-power kW-class fiber lasers
, 2022 Paper 1126025, 10 S.Within the EKOLAS consortium, which is part of the BMBF-funded EffiLAS (Efficient high-performance laser beam sources) research initiative, we are developing fiber Bragg gratings (FBG) directly written into multimode fibers.
