Bragg Grating Waveguide Array Ultrafast Laser Inscribed into the Cladding of a Flat Fiber
MATEC Web of Conferences, 2013 We report the fabrication and initial characterization of a waveguide sensor array in the cladding of a flat fiber. The sensor, designed to independently measure the strain on three Bragg grating waveguides, exploits the true three dimensional ...

Preparation of Photosensitive Fibers for Weak Fiber Bragg Grating Arrays
Physics Procedia, 2013 AbstractTwo kinds of photosensitive fibers were prepared for on-line writing weak FBG arrays. A Ge/B co-doped fiber was designed for high single-pulse photosensitivity and a Ge highly-doped fiber was applied for low transmission loss. The experimental results show that the weak FBG arrays written on the Ge/B co-doped fiber have more uniform spectral ...

Advanced Functional Materials, EarlyView.Sea cucumber mutable collagenous tissue (MCT) is a remarkable collagen‐based material which can rapidly undergo large changes in stiffness through transiently bound effector proteins. Here, we investigate the hierarchical structure and mechanical response of MCT from Cucumaria frondosa across length scales with a wide range of methods, also exploring ...

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics
Advanced Materials, EarlyView.The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and
