This work presents an experimental analysis and comparison of the performance of quasi-randomly distributed reflectors inscribed into a single-mode fiber as a sensing mirror both in C- and L-band. Single-wavelength emission ...
Detection of ethanol in human breath using optical fiber long period grating coated with metal-organic frameworks
(MDPI, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
An optical fiber sensor for ethanol detection in exhaled breath has been developed. It has been fabricated by functionalizing a Long Period Grating with a metal-organic framework, ZIF-8. The sensor’s response was tested ...
Gas sensor based on lossy mode resonances by means of thin graphene oxide films fabricated onto planar coverslips
