چکیده
Erbium-doped fiber amplifiers ~EDFAs! have been intensively studied for wavelength-division-multiplexing ~WDM! communication systems. The stabilization of the amplifier gain against the input signal-power variation is one of the key issues for WDM networks. The gainstabilizing technique using a passive optical feedback device, such as a bandpass filter or a fiber Bragg grating, has been reported. The gain medium, in conjunction with the

Observation of Raman Gain in Reduced Length of Bismuth Erbium Doped Fiber
Raman amplification of a 49 cm Bismuth oxide (Bi2O3) as a nonlinear gainmedium based erbium doped fiber amplifier (EDFA) is reported in new and compactdesign in near infrared spectral regions. The bismuth glass host provides theopportunity to be doped heavily with erbium ions to allow a compact optical gain fiberamplifier design by using reduced fiber length and the 1480...
متن کاملGain-clamping erbium-doped waveguide amplifier module using optical feedback technique
A forward optical feedback technique for gain-clamping erbium-doped waveguide amplifier has been proposed and experimentally investigated. Three different saturated tones are selected in this proposed structure over the operation range from 1530 to 1550 nm to realize the amplification behaviors. Therefore, a dynamic range of input signal power from 9 to 40 dBm at 1552 nm is obtained when differ...
متن کاملGain, Noise Figure and Efficiency Characteristics of an L-Band Erbium Doped Fiber Amplifier
In this work, the construction of a single stage L-band erbium-doped fiber amplifier which incorporates a short 5.1 m erbium doped fiber coil is described. Gain and noise figure measurements as a function of forward, backward and counter-propagating CW 1480 nm pumping schemes at different pump power levels are presented. Further, the Erbium Doped Fiber Amplifier (EDFA) power conversion efficien...
متن کاملTunable gain-clamped double-pass Erbium-doped fiber amplifier.
A tunable, gain-clamped (GC) double-pass Erbium-doped fiber amplifier (EDFA) with a linear laser-cavity configuration has been demonstrated. It solves the problems existing in the conventional linear-cavity GC-EDFA based on two fiber Bragg gratings (FBGs), in which the clamped-gain is very difficult to be tuned. In the new GC-EDFA, the lasing oscillation for clamping the gain is produced in a l...
