Abstract :
The authors describe a fiber-optic link architecture which minimizes noise figure by combining the two complementary outputs of a Y-fed coupler electrooptic modulator in such a way that the optical noise cancels in a balanced receiver module. The demonstration link exhibits 9.5-dB insertion loss and 13.5-dB noise figure at 900 MHz.<>
