Abstract :
The time delay for light transmission in a coupled microring waveguide structure is calculated from the phase shift of the transmission coefficient obtained by Pade approximation with Baker´s algorithm from FDTD Output. The results show that the Pade approximation is a powerful tool for saving time in FDTD simulation.
