The holographic-grating based wavelength-controlled true-time-delay devices are presented in the paper. The optical true-time-delay can be continuously controlled by continuously tuning the wavelength of a single laser within the devices. The dispersion ability of the devices is greatly enhanced by increasing the diffraction angles of the holographic gratings. The fabricated true-time-delay devices work within 1550nm region. The loss performance of the devices were calculated and measured. The wavelength-controlled true-time-delay was also characterized both theoretically and experimentally.
