Title: Optimal Mode Coupling in simple planar waveguides

Abstract:
Conventional dielectric channel and strip waveguides are still the primary
devices for localizing and moving optical signals in chip-level integrated
photonic structures. A fundamental engineering problem associated with
these structures is how to efficiently couple energy into and out of the
waveguide.
An approach for designing efficient waveguide couplers by formulation and
numerically solving an associated mathematical optimization problem is
proposed.
