Abstract

Computer-aided design, analysis and numerical simulation have more and more often been used in the design and simulation of integrated optical components. BPM, one of the popular numerical methods is effective at the Slowly Varying Envelope Approximation (SEVA). But the current integrated device is so complex that the SEVA is not satisfied any more. Finite-difference Time Domain (FDTD) is a method by which the Maxwell equations are directly discretized and resolved without any approximation. With continuous increasing of computing power, FDTD, as a powerful tool in microwave technology, can be employed in the optical domain. The general theory of FDTD and its basic formulation in orthogonal coordinate system are given at the beginning of this paper. Then the absorbing boundary condition and the criterion for stability are also discussed. At last the validation of this method is analyzed and a conclusion is drawn through a practical example to simulate the propagation in a film wave-guide of a diode laser light with wavelength around 1.55 micrometers . This method could be used in the design and analysis of other optical integrated device.
