Abstract
An optical amplifier assembly integrating wavelength selective input and output filters. Integration of wavelength selective filters with a doped fiber optical amplifier stage provides a modular amplifier for use in wavelength division multiplexed optical communication systems. In one embodiment, a center tap provides access to the selected light signal after a first amplifier stage, allowing signal modification before returning the light signal to a second amplifier stage of the integrated amplifier. In a further embodiment, a pump interconnect is provided between the first and second amplifier stages to allow operation of both amplifier stages from a single pump light source.
