Abstract
An optical system may include a polarization beam splitter having an input that receives multiple optical signals, a first output and a second output. The first output may provide components of the multiple optical signals having a first polarization. The second output may provide components of the multiple optical signals having a second polarization. The optical system may include a rotator having an input that receives the components to rotate the first polarization such that each of the components has the second polarization, and an output to supply components as rotated components.The optical system may also include an optical circuit including a substrate. The rotator may be separate from the substrate. The optical circuit may include an optical demultiplexer circuit provided on the substrate to receive the rotated components and the components.
