Abstract
A coherent optical receiver that receives an optical PSK-modulated signal includes optical elements that combine the optical PSK-modulated signal and an optical local-oscillating (LO) signal and splits the combined optical signals into multiple parts that have a predefined phase offset relative to one another. The receiver further includes at least one thyristor and control circuitry operably coupled to terminals of the at least one thyristor. The control circuitry is configured to receive the multiple parts of the combined optical signals and controls switching operation of the at least one thyristor according to phase offset of optical PSK-modulated signal relative to the optical LO signal.
