摘要：

We describe an analytic method for fully characterizing the gain of an erbium-doped fiber amplifier (EDFA) that is based on easily measured monochromatic absorption data. The analytic expressions presented, which involve the solution of one transcendental equation, can predict signal gains and pump absorptions in an amplifier containing an arbitrary number of pumps and signals from arbitrary directions. The gain of an amplifier was measured over a range of more than 20 dB in both pump and signal powers with the results agreeing to within 0.5 dB of the theory. Although the results described apply explicitly to EDFA's pumped in the 1480-nm region, they are also applicable to EDFA's pumped in the 980-nm region. Our method is valid whenever the gain saturation by amplified spontaneous-emission noise can be neglected, which is typically the case for amplifiers with less than about 20 dB of gain. © 1990 IEEE
