Topology optimization is a promising method for systematic design of optical devices. As an example, we demonstrate how the method can be used to design a bend in a two-dimensional photonic crystal waveguide with a transmission loss of less than 0.3% in almost the entire frequency range of the guided mode. The method can directly be applied to the design of other optical devices, e.g., multiplexers and wave splitters, with optimized performance.
