Abstract
An optical device may include a package having a first port for receiving signal light, a source for providing pump light, a combiner for combining the signal light and the pump light into combined light, a second port for sending the combined light, a third port for receiving amplified light, and a free-space optical system for filtering amplified signal light from the amplified light, and a fourth port for sending the amplified signal light. The free-space optical system may include beam shaping optics that enlarge a beam size of the amplified light prior to the filtering.
