Abstract
An L band optical amplifier in disclosed. The amplifier includes a signal line for transmitting a signal light in a first direction. The signal line includes an input, an output disposed optically downstream of the input, and a first amplifying gain medium optically disposed between the input and the output. A first laser is optically aligned with the first amplifying gain medium to transmit a first pump light to the first amplifying gain medium toward the output. A first reflector is disposed along the signal line between the first amplifying gain medium and the output to reflect a first bandwidth of light from the first amplifying gain medium back into the first amplifying gain medium. A second laser is optically aligned with the first amplifying gain medium to transmit a second pump light to the first amplifying gain medium toward the input. A second is reflector disposed along the signal line between the first amplifying gain medium and the input to reflect a second bandwidth of light, different from the first bandwidth of light, from the first amplifying gain medium back into the first amplifying gain medium.
