Localized Temperature Monitoring in Mouse Brain during Light Delivery via a Non‐Planar Tapered Fiber‐Integrated µRTD Sensor

Advanced Materials, EarlyView.
We report a multifunctional tapered optical fiber integrating a conformal micro‐resistance temperature detector (µRTD) for local, real‐time thermometry during optical stimulation. The platform combines light‐delivery and temperature sensing within a minimally invasive footprint, enabling detection of sub‐degree cortical heating under representative ...

Non‐Continuous Iridescent Variable Structural Color Based on Metallic Surface Periodic Structures

Advanced Materials Interfaces, EarlyView.
This study presents an ink‐free laser nanofabrication technique that generates periodic arched microstructures on titanium surfaces, achieving non‐continuous iridescent dual‐color switching. The ridge and side flanks of these structures possess distinct oxide film thicknesses, enabling angle‐dependent selective reflection of specific wavelengths.

Polymer optical fibre Bragg gratings based fibre laser

Optics Communications, 2006
Abstract For the first time the fibre laser constructed from a polymer optical fibre Bragg grating is reported. The single frequency laser with the peak power of −5 dBm and signal to noise ratio greater than 45 dB has been achieved. Further examination demonstrates the excellent characteristics of the fibre laser. First, the fibre laser can be easily
