Abstract :
In conclusion, a TTD beamforming system that can provide continuous beam steering using a tunable multiwavelength laser source with equally increased or decreased wavelength spacing has been proposed and experimented. The experimental results showed when the wavelengths were tuned with equally increased wavelengths spacing, equally increased time delays were obtained.
