Paper Abstract

In this paper, multiwavelength erbium-doped fiber laser (EDFL) by use of fiber Bragg gratings (FBGs) with different tilt angles in single mode fibers (SMFs) is demonstrated. The offset spliced FBGs are employed as lasing wavelength selectors. FBGs with 2° and 8° tilt angles can produce dual- and multi-wavelength oscillations, respectively. A nonlinear optical loop mirror is incorporated in the laser cavity to stabilize the multiwavelength oscillation at room temperature. The difference in coupling characteristics when offset launched between tilted FBGs in SMFs and uniform/tilted FBGs in multimode fibers are discussed.
