Paper Abstract

The operation of a passively mode-locked erbium-doped fiber ring laser in two-color pulse mode has been experimentally observed. The experiments demonstrate that the wavelengths of two-color pulses can be switched among three wavelength bands. Through carefully controlling the polarization states of the laser cavity, various modulation patterns of the two-color pulses are obtained, which are due to the interaction of two different-wavelength pulses. Single- and three-color pulses are also observed. Multiwavelength oscillation is ascribed to the wavelength-dependent transmission induced by birefringence, and can synchronously mode-lock through nonlinear polarization rotation.
