.Switchable dual-wavelength erbium-doped fiber laser with a tilted fiber grating[J].Optoelectronics Letters,2007,3(1):27-29 Switchable dual-wavelength erbium-doped fiber laser with a tilted fiber grating JIN Long KAI Gui-yun XU Ling-ling LIU Bo ZHANG Jian LIU Yan-ge YUAN Shu-zhong DONG Xiao-yi Institute of Modern Optics, Nankai University, Tianjin 300071, China Abstract:       A dual-wavelength erbium doped fiber laser with a tilted fiber Bragg grating and photonic crystal fiber is proposed and demonstrated. In the laser,a 2W EDFA provides gain for all the laser lines; the highly nonlinear photonic crystal fiber introduces dynamic energy transfer between the two wavelengths caused by four wave mixing effect,so that a stable dualwavelength oscillation at room temperature is implemented. Different switching modes can be achieved by adjusting the lateral offset between the fiber grating and the guiding single mode fiber or by varying the state of polarization in the laser cavity. The maximum of output power of the laser has reached 314 mW. Hits: 3761 Download times: 231 View Full Text    Download reader
