Abstract

This paper presents a new three-wavelength ring laser using one erbium-doped fiber amplifier. The simultaneous output of three lasing wavelengths is achieved by controlling the gains of different filters through utilizing a cascaded fiber Mach-Zender interferometer (MZI) with the triangular-shaped interference transmission spectrum. The key advantage of the proposed system over existing technologies is that the output is channel-wavelength selectable. Each channel can be tuned individually from one channel wavelength to the other. The channel wavelengths are selectable over the range of 1522-1665nm.
