Development of Finite Difference Numerical Models for Photonic Guided-wave Devices (2/3)

This research concerns improvement and development of several finite
difference (FD) numerical models as tools for studying various photonic guided-wave
devices, including improvement and applications of our full-vectorial FD waveguide
mode solver, development of time-domain beam propagation method (FD-BPM),
development of 2-D finite difference time domain method, and continuous research
on fused fiber-optic couplers. The results of four topics of study obtained in the
second phase of this research are briefly described respectively in this report.
