Abstract :
We have designed a very low cost, flat gain L-band EDFA, by employing a simple FBG and the bi-directional pumping scheme with only one uncooled 980 nm LD. The flat gain of 17 dB, up to the total output of 13(15.4) dBm at 97(150) mW of 980 nm pump, is obtained over 30 nm with less than +/- 0.5 dB gain variations. In addition, efficient and simple gain clamped L-band EDFA is demonstrated.
