Abstract

A method for reliable fiber Bragg grating peak detection compatible with spectrometric demodulation schemes is presented. High immunity to differential losses and independency on the threshold settings was achieved. The effectiveness of the demonstrated method was corroborated by a 3σ accuracy of 2pm determined over 10⁹ samples of 100 resonant peaks multiplexed in [1500; 1600] nm spectral range acquired throughout a year.
