Abstract
Embodiments of the present disclosure may comprise a coherent optical receiver, where the coherent optical receiver comprises a PCSEL that generates a first and a second light beam. In accordance with various embodiments, the physical emission direction of the first light beam may be at an angle of 180 degrees, or 180 degrees plus/minus 10 degrees in some instances, to the physical emission direction of the second light beam. Embodiments may also comprise a first hybrid receiver that receives a first portion of an input light signal to the coherent optical receiver and the first light beam as a local oscillator signal, generating one or more first optical hybrid receiver output signals. Embodiments may also comprise a second hybrid receiver that receives a second portion of the input light signal to the coherent optical receiver and the second light beam as a local oscillator signal, generating one or more second optical hybrid receiver output signals.
