Abstract
In an embodiment, a polarization-dependent loss (PDL) compensator includes a substrate, an anti-reflective coating, and a partial reflective coating. The substrate has an input surface and an output surface opposite the input surface. The anti-reflective coating is formed on the output surface. The partial reflective coating is formed on the input surface. The PDL compensator may include PDL that depends on an incident angle of an optical signal with respect to the partial reflective coating.
