Stability and linewidth (FWHM & 20-dB) measurements of a tuneable, high power, narrow linewidth multiwavelength Hybrid Cavity Semiconductor Fibre Ring Laser (HC-SFRL) are presented. The laser incorporates a SOA, a polarization controller (PC), and a tuneable optical filter. The ring cavity itself is composed of Single Mode Fibre (SMF) and a 1-m long Polarization Maintaining Fibre (PMF). The laser is capable of single, dual and triple lasing wavelengths with ultranarrow wavelength spacing (less than 30 pm) with good stability for periods over 2 hours.
