Abstract :
All-fibre distributed feedback (DFB) lasers providing continuous tuning over 27 nm are demonstrated for the first time. Extended wavelength coverage of the lasers is obtained using a simple bend-tuning technique which delivers undistorted outputs over the full tuning-range. We believe that the demonstrated devices are highly placed for application as tunable sources in future dynamic WDM optical communication networks that require all-optical wavelength tunability.
