Paper Abstract

The performance of a 1540 nm pigtailed VCSEL has been characterized in terms of output power, frequency range and rate of wavelength sweeping for its application in fibre Bragg grating interrogation. Results are presented for the laser operating under optimized control when used to illuminate a single FBG mounted under tension between a fixed plane and a loud speaker cone subject to a range of frequencies at arbitrary amplitudes and transients. The ultimate objective is to extend the set-up to a parallel fibre topology supporting 8 FBGs with equal wavelengths.
