Abstract 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.
