Coupled chirped vertical gratings are proposed for on-chip group velocity dispersion engineering. The device circumvents the need for directional couplers or circulators to redirect compensated data. Finite difference time domain simulations and experimental verification of fabricated devices are performed. Dispersion values of up to //8.4×105 psnmkm are demonstrated.

    One of the main techniques for the Finite-Difference Time-Domain (FDTD) analysis of dispersive media is the Recursive Convolution (RC) method. The idea here proposed for calculating the updating FDTD equation is based on the Laplace transform and is applied to the Drude dispersion case. A novel...
