Abstract

A multiwavelength fiber laser is constructed with an elliptical core erbium-doped fiber serving as an anisotropic gain medium. A broadband fiber reflector and a Sagnac loop reflector form a Fabry-Perot resonant cavity. Three lasing wavelengths are obtained which are stable over an hour at room temperatures. With one of them as reference wavelength, we can switch the other two by a polarization controller. The lasing wavelengths are also tunable. The effects of the anisotropic gain behavior of the erbium-doped fiber are also explored.
