| Research Abstract |
6-GHz continuous signal was coherently synthesized with in-phase and reversed-phase by two optical beats. 6-GHz continuous signal was synthesized spatially by adjustment of SMF length or DFB-LD wavelength. Measured power of 6-GHz signal synthesized with in-phase was increased by almost 6dB compared with that generated by one optical beat. Furthermore, 20-GHz continuous signal was coherently synthesized by two optical beats and detected by SBD detector. Measured power of 20-GHz signal synthesized with in-phase was increased by around 4 dB compared with that generated by one optical beat.
In addition to the coherent synthesis, 6-GHz continuous signals were incoherently synthesized by two optical beats. The power of incoherently synthesized 6-GHz signal was increased by 3dB compared with that generated by one optical beat. 6-GHz continuous signals were also synthesized spatially using dipole antennas and the microwave power was increased by almost 3dB.
