MULTIWAVELENGTH TUNABLE ERBIUM-DOPED FIBER LASER BASED ON FABRY-PEROT FILTER AND MACH-ZENHDER INTERFEROMETER

摘要

A tunable multiwavelength erbium-doped ring cavity fiber laser based on a Fabry-Perot filter and Mach-Zenhder interferometer is proposed. A tunable single wavelength laser is realized from 1526.8 to 1558.6 nm, and the space interval and peak power shift are less than 2.6 nm and 0.8 dBm, respectively. A dual- and tunable triple-wavelength laser are achieved, and the power fluctuation of the dual- and triple-wavelength lasers is less than 0.153 and 1.28 dBm, respectively, at room temperature within a 20-min scan time.
