Paper Abstract

In this work, the inscription in few seconds of a Bragg grating array in undoped PMMA mPOF using the phase mask technique is reported. The fast growth was possible through the use of a 248 nm UV laser, with suited laser parameters, allowing the creation of a core refractive index modulation without damaging the fiber surface. The Bragg gratings were written in the IR region presenting good spectral properties, achieving for the best case 30 dB reflectivity and 0.2 nm bandwidth. The Bragg grating array was characterized to strain and results are in agreement with the values reported in literature.
