Abstract
We present a novel approach to the sensitivity analysis of 3-D structures
using the full vectorial beam propagation method (FVBPM). Using no extra simulations,
the sensitivities of the response with respect to all design parameters are
obtained regardless of their number. Our approach is exploited to calculate
the sensitivities of the propagation constants of multimode waveguides. It
is also applied to the 3-D imaginary distance FVBPM (ID-FVBPM) and utilized
to extract the sensitivities of the mode parameters. The calculated sensitivities
are then utilized within a gradient-based optimization algorithm to illustrate
the application of the obtained sensitivities. The accuracy of our approach
is verified through a comparison with the expensive central finite difference
applied directly at the response level.
