A nine bit comb shaped delay line consisting of Mach Zhender Interferometer (MZI) and MMI coupler is realized on Silicon platform at 1550nm.The device spans 35μm and offers a variable delay from 5fs to 40fs.Simulated Insertion loss of the device is -25dB. FDTD method is used for the analysis. The delayed signal is fed to the antenna array and the variation in the radiation pattern is observed.
