Paper Abstract

The concept of optimized waveguide mode control elements allows for the design of improved components such as mode converters and waveguide transitions. This concept can also be applied to the realization of a new type of waveguide phase shifter through the modification of a waveguide geometry. Some examples for the optical control of a waveguide dimension in several different types of waveguide are provided. These designs require accurate numerical electromagnetic solvers and the use of nonlinear optimization tools, resulting in an iterative process where constraints such as bandwidth and manufacturability can be imposed.
