• Finite-difference time-domain (FDTD) method
• integrated optics
• moving computational window
• optical waveguides
• second-harmonic generation (SHG)

The model equations of the vectorial time-domain simulator of second-harmonic generation in integrated optical structures have been reformulated by extracting the signal carrier. The moving computational window technique is then used to ease the computational burden in the finite-difference time-domain solution. Results show that the technique provides considerable savings in computation power especially for long propagation distances.
