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 ...

FBG optimization using spline encoded evolution strategy

Journal of Microwaves, Optoelectronics and Electromagnetic Applications
This paper presents an encoding scheme adapted for Fiber Bragg Grating (FBG) optimization using metaheuristics. The proposed encoding scheme uses spline approximations in order to build softened refractive index profiles from few encoded parameters. This

Simulation of Fiber Bragg Grating (FBG) as A Strain Sensor

International Journal for Research in Applied Science and Engineering Technology, 2023
Abstract: In this study, the Fibre Bragg grating (FBG) is modelled, simulated, and characterised with respect to maximum reflectivity, bandwidth, the impact of applied strain on the wavelength shift, λB, and the wavelength shift sensitivity with strain for an optical sensing system.
