| Abstract: | Radio over fiber（ROF） system has been successfully applied in mobile communication, intelligent traffic control, indoor signal coverage, and other fields. Millimeter-wave generation as one of the key technologies in ROF has been greatly developed. The new technologies based on external modulation techniques, optical heterodyne techniques and up-conversion technology appear constantly. Starting with the principle of ROF some usual methods for millimeter-wave generation are studied, and the advantages and disadvantages are also analyzed. Finally applications of ROF are introduced briefly. |
