Abstract

Irregular waveguide elements in a silicon-on-insulator platform that allow new device concepts are introduced. Specific designs are achieved using a multiresolution optimization strategy where the waveguide width is varied in stepwise increments. Simulation results are given for high-efficiency waveguide mode converters, power splitters, and waveguide transitions operating at $1.55\mu \mathrm{m}$. The degrees of freedom available permit these functions and small dimensions, making these devices candidates for optical integrated circuits.
