Paper Abstract

A stable, tunable, CW, narrow-linewdith ring distributed feedback (DFB) fibre laser fabricated in erbium-doped photonic crystal fibre is demonstrated. Wavelength tuning of this device using a piezoelectric transducer was utilized to probe the P11 molecular absorption band of acetylene (C2H2) with a resolution of 0.45pm. Furthermore, by applying an AC voltage this absorption band could be continually-swept, allowing square-wave modulation of the DFB output at repetition rate of 500Hz.
