Integrated component for an optical amplifier

An optical package, comprising:

• a plurality of ports including:
• a first port for receiving signal light,
• a second port for sending combined light,
• a third port for receiving amplified light, and
• a fourth port for sending amplified signal light;
• a source for providing pump light;
• a combiner for combining the signal light and the pump light into the combined light;
• and
• free-space optics for filtering the amplified signal light from the amplified light,
• wherein the free-space optics include beam shaping optics for resizing the amplified light.

A method, comprising:

• receiving signal light by a first port of an optical device;
• providing pump light by a source of the optical device;
• combining, by a combiner of the optical device, the signal light and the pump light into combined light;
• sending the combined light by a second port of the optical device;
• receiving amplified light by a third port of the optical device;
• resizing, by beam shaping optics of the optical device, a beam size of the amplified light,
• wherein the beam shaping optics are included in a free-space optical system of the optical device;
• filtering, by the free-space optical system of the optical device and after the resizing, amplified signal light from the amplified light;
• and
• sending the amplified signal light by a fourth port of the optical device.
