文摘

Multiwavelength Erbium-doped fiber ring lasers using two fiber filters inserted into the laser cavity is reported. The first fiber comb filter is a Mach-Zender interferometer consisting of two concatenated fiber tapers whose transmission bands determine the lasing wavelengths. The second filter is a tapered fiber which acts as a broadband fiber filter that reshapes the Erbium-doped fiber gain spectrum, and can be tuned by S-bending. Both filters are fabricated on the same fiber thus providing a cheap and very simple method to obtain tunable multiwavelength laser generation.
