FIELD: physics.
SUBSTANCE: optical coherent receiver in accordance with the embodiment has a heterodyne configuration and a homodyne configuration in accordance with another embodiment. Each configuration employs multiple feedback signals and analogue-to-digital conversion to optimise response to the modulated optical input signal, provision for RF output I- and Q-channels separately.
EFFECT: more reliable reception.
