摘　　要：We report on the realization of optical true-time delay （TTD） by a two-dimensional photonic crystal waveguide （PCWG）. Design and fabrication of the PCWG are investigated. The spectral dependence of the group delay is measured by detecting the phase shifts of a 10 GHz modulating signal, and a maximum delay of 25±2.5 ps is obtained.We report on the realization of optical true-time delay （TTD） by a two-dimensional photonic crystal waveguide （PCWG）.
