This paper reports the design optimization of a novel tunable dual wavelength erbium doped fiber ring laser. The effects of pump wavelength, active fiber length, and coupling ratio on threshold pump power, output power, and side mode suppression ratio (SMSR) of the lasers are investigated. Pumping a
## Abstract A tunable dualβwavelength Erβdoped fiber laser (EDFL) is proposed and demonstrated. By applying axial and lateral strain simultaneously on the fiber Bragg grating (FBG), the absolute wavelength and wavelength spacing of the Erβdoped fiber laser can be tuned continuously. Β© 2004 Wiley Pe
