| Abstract: | We proposed a novel method of optical beam forming network based on broadband optical source.Vector signal of nQAM was transmitted over 20 km and delayed by controlling.True time delay of 4 lines and 5 bit precise was distributed.Less than 0.5 dB ripple of amplitude and 1ps true time delay precise was accomplished. |
