Abstract
The time-domain beam propagation method
(TD-BPM) has been implemented and analyzed using several
iterative numerical techniques to model the propagation
of ultra short pulses in optical structures. The methods
depend on one-way non-paraxial time domain propagation
that use Pade approximant formulation. Several numerical
tests showed that the iterative TD-BPM techniques are
very stable and converge using few
iterations.
From accuracy assessment compared to the FDTD, it has
been observed that the longitudinal and the temporal
steps sizes can be a number of orders of magnitude
larger than the FDTD step sizes with little percentage
difference. Computer performance analysis showed the
TD-BPM is well suited for long dielectric structures
interaction of short and ultra short pulse
propagation.
