Inverse design of a three-dimensional nanophotonic resonator

The inverse design of a three-dimensional nanophotonic resonator is presented. The design methodology is computationally fast (10 minutes on a standard desktop workstation) and utilizes a 2.5-dimensional approximation of the full three-dimensional structure. As an example, we employ the proposed method to design a resonator which exhibits a mode volume of 0.32(lambda/n)(3) and a quality factor of 7063. (C) 2011 Optical Society of America
