Abstract

This paper presents the application of a new erbium-doped fiber ring laser configuration for the multiplexing of intensity sensors. The proposed scheme exploits two separated branches to generate simultaneous emission at four different wavelengths. Fiber Bragg gratings are used to select the operating wavelengths within the erbium-doped fiber ring. The first branch presents a serial configuration to generate the reference lasers. The second branch exploits a tree configuration and includes the optical intensity temperature sensors. A comparison between both branches of the same setup is carried out, and their temperature and time stability is shown by varying the erbium doped fiber.
