Paper Abstract

Serving as a frequency selective device, comb filter is a very important component to the multiwavelength erbium-doped fiber laser. There are all kinds of comb filters, among which the Mach–Zehnder interferometer (MZI) is the commonly used one. Since each types of Mach–Zehnder interferometers have its output features, then the study of its influence to the output characteristics of multiwavelength erbium-doped fiber laser is necessary. In this paper, the filtering properties of three basic Mach–Zehnder interferometer are discussed, including single-pass MZI, dual-pass MZI, dual-pass MZI with a optical isolator embedded into the second loop. Furthermore, the working principle and tunable operation of the tunable modified dual-pass MZI are analyzed. Above all, the influence of the four types of MZI to the output characteristics of multiwavelength erbium-doped fiber laser is experimentally studied. The results of this paper are helpful to understand the working principle of these comb filters and improve the output performance of multiwavelength erbium-doped fiber laser.
