ABSTRACT:
A hybrid, erbium doped fiber amplifier device has a dynamic gain tilt that is less than the gain tilt of any of the constituent fibers. The hybrid amplifying device has at most one less pumping source than the number of constituent waveguides of the device. The hybrid device automatically provides an effective change in the pump distribution among the constituent doped waveguide sections so as to achieve a readjustment of the relative gains of the constituent sections. As such, a change in the aggregate gain of the hybrid device will be as nearly spectrally uniform as possible over a range of gain values compared to the constituent doped waveguides. A method for constructing a hybrid optical amplifying device having improved dynamic gain tilt is also provided.
