Optimum Pumping Configuration for L-band EDFA incorporating Selective Wavelength Auxiliary ASE from C-band EDFA

We present a thorough investigation of the optimum pumping configuration for L-band EDFA in order to maximize signal gain and minimize noise figure with forward and backward ASE pumping, by incorporating the selective property of the pump wavelength band from C-band EDFA section. A simulation of three-level rate equation has been carried out using 980 nm primary pump, 1570 nm as Lband signal wa...

Tunable 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...

Double-pass high-gain low-noise EDFA over S- and C+L-bands by tunable fundamental-mode leakage loss.

We demonstrate a high-gain low-noise double-pass tunable EDFA over S- and C+L-bands by discretely introducing fundamental-mode leakage loss in a 16-m-long standard C-band Er(3+)-doped fiber. The amplified spontaneous emission at the wavelengths of longer than 1530 nm can be substantially attenuated by the ASE suppressing filters to maintain high population inversion and to squeeze out the optic...

S-band gain-clamped grating-based erbium-doped fiber amplifier by forward optical feedback technique.

An S-band gain-clamped erbium-doped fiber amplifier module, employing a fiber Bragg grating to serve as a reflected element for lasing a saturated tone injected into the module by forward optical feedback method, is proposed and investigated experimentally. Moreover, the performance and behavior of the gain and noise figure in the proposed gain-clamped S-band fiber amplifier have also been disc...
