Optical circuit configurations to enable bidirectional optical ports

Abstract

The techniques described herein relate to systems, apparatus, articles of manufacture, and methods for optical circuit configurations to enable bidirectional optical ports. An example optical transceiver includes a modulator configured to output a first modulated optical signal by modulating a first optical signal from a laser source, a polarization rotator configured to output a second modulated optical signal by changing a first polarization state of the first modulated optical signal to a second polarization state, and a polarization splitter comprising a bidirectional port, the polarization splitter configured to receive, by the bidirectional port, the first optical signal for output to the modulator, and output, from the bidirectional port, the second modulated optical signal.
