“…The other is the all-optical gain control technique [4]. A simple and effective way to clamp the gain is to utilize the lasing mechanism by using a couple of gratings at the EDF ends [5], [6] or by forming an optical ring to establish lasing oscillation [7], [8]. However, in most works, the low noise figure (NF) and the signal output without lasing power cannot be satisfied simultaneously in the all-optical GC lasing amplifiers.…”

A new design of all-optical gain-clamped L-band double-pass (DP) erbium-doped fiber amplifier (EDFA) has been proposed and demonstrated, in which the input port and the odd-channel output port of an interleaver are connected with the DP configuration EDF through a circulator to form lasing ring cavity for clamping gain, and the even port is utilized to export the amplified signals. The low noise figure can be achieved because the lasing power copropagates with the signals, and it is exported separately from the amplified signal thanks to interleaver. Meanwhile, the fiber Bragg grating incorporated in DP configuration suppresses the backward amplified spontaneous emission generation, and therefore improves efficiently the gain and lowers the noise figure. In such a way, the clamped gain of 16.3 dB with a variation below 0.2 dB and noise figure below 5 dB are achieved in the new L-band all-optical gain-clamped EDFA.
