Abstract

Multiwavelength laser operation of an inhomogeneously broadened Er-doped twincore fibre loop laser is demonstrated. Equal output power, separation 0.5nm and linewidth <10kHz was confirmed for each mode in a 3 wavelength laser. Up to 8 wavelength operation has been observed, demonstrating that twincore EDFAs can provide channel equalisation in an 8-channel multi-amplifier optical network.
