Robust topology optimization of three-dimensional photonic-crystal band-gap structures
Han Men, Karen Y. K. Lee, Robert M. Freund +2
We perform full 3D topology optimization (in which "every voxel" of the unit cell is a degree of freedom) of photonic-crystal structures in order to find optimal omnidirectional ba…
Fabrication-Adaptive Optimization, with an Application to Photonic Crystal Design
Han Men, Robert M. Freund, Ngoc C. Nguyen +2
It is often the case that the computed optimal solution of an optimization problem cannot be implemented directly, irrespective of data accuracy, due to either (i) technological li…
Band Gap Optimization of Two-Dimensional Photonic Crystals Using Semidefinite Programming and Subspace Methods
Han Men, Ngoc-Cuong Nguyen, Robert M. Freund +2
In this paper, we consider the optimal design of photonic crystal band structures for two-dimensional square lattices. The mathematical formulation of the band gap optimization pro…
