Abstract

tunable multi-wavelength erbium-doped ring cavity fibre laser based on a cascaded Sagnac loop comb filter was developed. The hybrid filter is composed of two Sagnac loops with different lengths of polarization-maintaining fibres. Tunable and stable single-, double-, and triple-wavelength lasers were realised experimentally with wavelength shifts and power fluctuations of <0.04 nm and <1.93 dBm, respectively. The side mode suppression ratio was >40.11 dB, and the 3-dB laser linewidth was <0.05 nm. Quadruple- and quintuple-wavelength lasers were achieved by adjusting the polarization controller, and the side mode suppression ratio was >38.56 dB..
