Abstract
An intracore Bragg grating and a broadband reflector are used as cavity end mirrors of a tunable Erbium-doped fiber laser where the Bragg grating serves the dual purpose of the tuning element and the sensor. This fiber laser sensor (FLS) is integrated with a wavelength demodulation system (WDS) to form a practical strain and temperature sensor. Laser tuning with both temperature and strain have been achieved and the data is presented. To further promote practical applications of the FLS, a two element fiber laser sensor array has also been designed and developed. Preliminary data indicates excellent stability and no cross-talk.Keywords
