Last decade, the research on multiwavelength erbium-doped fiber lasers (MWEDFLs) was increased dramatically due to its very interesting advantages and a wide range of applications. Many comb filters were proposed to lase multiwavelength from fiber lasers such as Fabry-Perot filter (FPT), photonic crystal fiber (PCF), and Sagnac loop mirror. However, all those filters suffer the disadvantage of less compactness. On the other hand, microfiber Mach-Zehnder interferometer which is fabricated from conventional single mode fiber (SMF) is considered to be the most compact designed to generate multiwavelength fiber lasers. In this paper, we have successfully generated four wavelengths centered at 1549.52 nm, 1553.2 nm, 1556 nm, and 1558.8 nm from erbium doped fiber the laser. Very good stability was observed when the output of the demonstrated laser investigated over one and half an hour. The proposed multiwavelength laser can be seen as a promising multiwavelength light source for various applications including wavelength division multiplexing (WDM) transmission, modern optical communication system, and optical fiber sensor network..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
