All-fiber Mach–Zehnder comb filter based on tapered fibers for wavelength switchable erbium-doped fiber lasers
A wavelength switchable erbium-doped fiber laser was constructed based on an all-fiber Mach–Zehnder interferometer (MZI) comb filter. The MZI consisted of a fiber with two tapers. An L-band erbium-doped fiber was used as the gain medium, and 1557.92, 1563.2, and 1568.06 nm single-wavelength and dual...
