Rjs. Pedersen et F. Ebskamp, NEW ALL-OPTICAL RIN SUPPRESSING, IMAGE REJECTION RECEIVER WITH EFFICIENT USE OF LO-POWER AND SIGNAL-POWER, IEEE photonics technology letters, 5(12), 1993, pp. 1462-1464
We propose an all-optical method of achieving suppression of local-osc
illator (LO) RIN, image rejection, and efficient use of signal and LO
power for a heterodyne receiver. Hence, only one photodetector is need
ed compared to four in the conventional optical-electrical image rejec
tion receiver.
