Abstract: | We propose and analyze a prototype of a 60 GHz millimeter-wave (mm-wave) generator. In the scheme, two lasers with a 70 GHz frequency interval serve as sources. Then a frequency-quadrupling feed-forward modulation technique is employed to generate two phase correlated sidebands with a 60 GHz interval. The desired sidebands can be selected by using standard optical interleavers. In our work, a 60 GHz mm-wave signal free of phase noise can be achieved. The employed technique can also be extended to frequency 8-tupling. |
