Abstract
The complex mode-matching method is applied to simulation of optical
waveguide structures with intersecting structures such as crossings and corners.
It is demonstrated that field propagating along the direction perpendicular
to the incident waveguide can be represented adequately by the complex modes
defined in the incident waveguide and, therefore, can be simulated accurately
by the complex mode-matching method. Power conservation is illustrated by
way of examples to prove the self-consistency of the complex mode-matching
method. Radiation field perpendicular to the incident waveguide axis in waveguide
crossings and corners is simulated by this method and validated by the finite-difference
time-domain method.
