Abstract :
We demonstrated optical phased array antenna based on true-time delay (TTD) beamforming for radio-over-fiber (RoF) using semiconductor optical amplifier (SOA) and tunable dispersion medium. In the case of the full range of beam direction, the required delay time per antenna element was 194 ps. As a result, the full true time delay was obtained by adjusting the dispersion value of the tunable dispersion medium (TDM) from -400 ps/nm to +400 ps/nm. We successfully achieved the high TTD performance for various output beam angles.
