Abstract
In accordance with a method for transferring optical signals to and from an optical component incorporated in a photonic integrated circuit (PIC), an incoming optical signal in a first polarization state is received at a splitter section of a polarization splitter rotator (PSR). The splitter section causes the optical signal to be directed to a first waveguide of a pair of waveguides of the PSR. One of the waveguides rotates a polarization state of an optical signal traversing therethrough into an orthogonal polarization state and the other waveguide maintains a polarization state of an optical signal traversing therethrough. The incoming optical signal is directed from the first waveguide to the optical component. An outgoing optical signal is received in a second waveguide of the pair such that the outgoing optical signal traverses the second waveguide and the splitter section to be output by the PSR.
