Abstract
We propose and demonstrate a novel four-wavelength erbium-doped fiber laser using four-wave mixing (FWM). By inserting a length of highly nonlinear photonic crystal fiber (HNPCF) in the laser cavity and using two fiber Bragg gratings as the wavelength-selecting components, four stable wavelengths with equal spacing have been realized at room temperature. The energy-conversion-induced loss caused by the FWM, which happens in the HNPCF among the two oscillating laser lines and the FWM products, is believed to contribute to the stable multiwavelength operation by suppressing the wavelength competition between the two laser lines.
