    Abstract: Methods, systems, and apparatus for optical communications. One of the apparatuses comprises a birefringent crystal configured to separate an incoming light beam input at a first port into component light beams having orthogonal polarization directions and directing the component light beams on respective paths to exit locations on the birefringent crystal; and a Faraday rotator positioned between the birefringent crystal and a beam folding optic assembly, wherein the Faraday rotator is positioned such that light beams exiting the birefringent crystal along a first path from a first exit location pass through the Faraday rotator before being incident on the beam folding optic assembly and that light beams exiting the birefringent crystal along a second path from a second exit location pass directly to the beam folding optic assembly without being incident on the Faraday rotator.

    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for optical communications. In one aspect, an optical amplifier includes an input port, a wavelength division multiplexing fiber coupled to a pump source and to a bar-cross switch, a first gain stage optically coupled between a first port of the bar-cross switch and to an output port, the first gain stage including a first gain flattening filter, and a secondary gain stage optically coupled between a second port and a third port of the bar-cross switch, the secondary gain stage including a second gain flattening filter. When in a bar-state of the bar-cross switch, the secondary gain stage is bypassed. And when in a cross-state of the bar-cross switch, the secondary gain stage and the first gain stage are applied to an input light beam.
