A Compact Design of 1310 Nm High Gain High Power Hybrid Fiber Amplifier

We construct a high gain high output power 1310 nm hybrid fiber amplifier, which can be use in telecommunication. It is a compact design combining a semiconductor optical amplifier (SOA) and a discrete Raman amplifier. It is hard to construct such amplifier by either using a SOA or a discrete Raman fiber amplifier with compact design. The amplifier is designed for a 1310 nm small signal input providing a high gain, and high output power with fast response.
