We propose and demonstrate a tunable multiwavelength erbium-doped fiber laser based on a polarization-maintaining photonic crystal fiber (PM-PCF) Sagnac loop filter. Stable, room-temperature operation is obtained by employing a nonlinear optical loop mirror. At a central wavelength of 1563.000 nm, w

## Abstract A novel swithcable dualโwavelength fiber laser using Pandaโtype photosensitive polarizationโmaintaining erbiumโdoped fiber (PMEDF) is proposed and experimentally demonstrated. Based on the integration of good photosensitivity and gain characteristics, two matched uniform fiber Bragg gra
A multi-wavelength erbium-doped fiber laser based on a Sagnac loop filter which is formed by a birefringent and highly nonlinear photonic crystal fiber (PCF), a 3-dB optical coupler and two polarization controllers is proposed. The PCF Sagnac loop filter is used as a comb filter and power-stabilizin
