Abstract
A micro Fabry-Perot (MFP) filter is proposed and fabricated by twisting a section of microfiber into two Sagnac loop mirrors. With the co-operation of this MFP filter and a section of highly nonlinear fiber, we propose and experimentally demonstrate a multi-wavelength Erbium-doped fiber ring laser (EDFRL) based on the inhomogeneous loss mechanism. When the pump current is set at 450mA, 22-lasering wavelengths with the identical wavelength space of 0.22nm and side-mode suppression ratio (SMSR) above 30dB are achieved. Within the period of one hour’s monitoring, the fluctuation of the output power is less than 0.943dB.
