Bragg Gratings in ZEONEX Microstructured Polymer Optical Fiber With 266-nm Nd:Y...
Pereira, L; Marques, C; Min, R; Woyessa, G; Bang, O; Humberto Varum; Antunes, PFDWe present the first fiber Bragg gratings (FBGs) inscription in ZEONEX-480R microstructured polymer optical fiber (POF) by employing the fourth harmonic (266 nm) of a Nd:YAG laser system. The gratings were produced in the L-band region by the phase mask method, in 270-mu m diameter POF samples connectorized with ferrule connectors (FCs). The results of three produced gratings are reported, showing good stabilit...
Interrogation Method with Temperature Compensation Using Ultra-Short Fiber Brag...
Pereira, L; Min, R; Woyessa, G; Bang, O; Marques, C; Humberto Varum; Antunes, PThe use of simpler and less bulky equipment, with a reliable performance and at relative low cost is increasingly important when assembling sensing configurations for a wide variety of applications. Based on this concept, this paper proposes a simple, efficient and relative low-cost fiber Bragg grating (FBG) interrogation solution using ultra-short FBGs (USFBGs) as edge filters. USFBGs with different lengths an...
