Abstract :
We have proposed optical true-rime delay beam-forming system using a DCF and a multi wavelength laser for phase array antenna. Total time delay for each wavelength band originated from group delay of a DCF and the fixed delay line. As a result, a DCF for 80 km NZ-DSF could be used to obtain the radiation angle of 180° by tuning the multi-wavelengths of laser in the proposed optical true-time delay.
