Abstract:
Embodiments include apparatuses, methods, and systems including a dynamic polarization controller (DPC) to receive a first light beam and a second light beam, to adjust a rotation of a state of polarization (SOP) of the first light beam and the second light beam to generate a third light beam and a fourth light beam, under the control of a first control signal, a second control signal, and a third control signal. The first control signal may be related to a phase difference between the third light beam and the fourth light beam, the second control signal may be related to an intensity difference between the third light beam and the fourth light beam, and the third control signal may be related to a rotation of a SOP of the third light beam and the fourth light beam. Other embodiments may also be described and claimed.
