Abstract :
A novel super-wide-band optical FM modulation scheme employing an optical heterodyne detection technique is proposed and demonstrated. Experimental results show that by applying this scheme to 40-channel AM video transmission, the power budget is expanded by approximately 10 dB at a CNR of 42 dB.
