Abstract:
1. An optical component comprising: a polarisation beam splitter (PBS) comprising a PBS output port, the polarisation beam splitter for receiving a first optical signal and for separating the first optical signal into a second optical signal and a third optical signal based on a polarisation of each of the second signal and the third signal; an output port for coupling with a first waveguide; a first lens for receiving the second optical signal and the third optical signal from the polarisation beam splitter and for propagating the second optical signal and the third optical signal to the output port for coupling with second and third waveguides respectively, the first lens including an opening therein for accommodating another optical component; and, a polarisation rotation component for rotating a polarisation of the second optical signal relative to the third optical signal and disposed within the opening of the lens.
