Abstract

Fibre DFB lasers exhibit many attractive features and being based on and around a fibre Bragg grating they exhibit the robustness in performance offered by these, together with inherent fibre compatibility They can readily be manufactured to operate in both a single longitudinal and single polarisation mode and strong preferential output has also been demonstrated by offsetting the phase-shift from the centre position. As the technology of fibre Bragg grating fabrication and manipulation have reached a level where the formation of complex refractive index profiles are possible, the step towards all-fibre systems is approaching at rapid pace. Multiple wavelength laser configurations have been demonstrated and applications of these to, for example accurate frequency referencing in wavelength division multiplexed (WDM) systems has been proposed. Some of the previous demonstrations have suffered from the necessity to reduce the homogeneous linewidth to allow stable, multiple wavelength operation. In this paper we demonstrate multiple wavelength Moire DFB fibre lasers operating CW at room temperature on two wavelength channels separated by 25, 50 and 100 GHz respectively The output power from each wavelength channel is ~0 dBm for ~60 mW pump power 980 nm.
