An optical amplifier is provided including means for receiving a first optical input data signal. A first pump laser is provided for generating a first optical pump signal, and a first optical multiplexer is adapted to receive and combine the first optical input data signal and the first pump signal. The first optical multiplexer thus forms a first composite optical signal that includes the first pump signal and the first optical input data signal. The optical amplifier includes a first substrate having a first doped optical fiber adhered to or embedded within the substrate. The first multiplexer couples the first composite optical signal to an input end of the first doped optical fiber so that the first composite signal is transmitted through the first doped optical fiber. At the opposite end of the first doped optical fiber a first optical demultiplexer is positioned to receive the first composite signal after the first composite signal has been transmitted through the first doped optical fiber. The first demultiplexer removes the first pump signal from the first composite signal and produces a first optical output data signal having increased optical power relative to the first optical input data signal.
