Abstract :
This paper presents a novel structure of an Er3+-doped fiber amplifier capable of bidirectional operation through the wavelength division multiplex method. The idea is to combine an Er3+-doped fiber, pump devices, optical isolators, and wavelength selective couplers so that two lightwaves having different wavelengths pass each proper isolator. The suitable structure was determined from experimental studies on several basic amplifier configurations. Optical gains of more than 25 dB were attained in both wavelength regions of 1.533 μm and 1.55 μm. Successful bidirectional operation of the amplifier was confirmed by means of a 2.488-Gbit/s-signal transmission experiment
