5 October 2009Tuneable ring-DFB PCF laser for ultra-high resolution spectroscopy
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.
