Invited/2009: Topology optimization in nano-photonics
Ole Sigmund1
1Department of Mechanical Engineering, Technical University of Denmark
Abstract: The topology optimization method is a finite element based design method that optimizes material distributions subject to various objective functions and constraints. The method was originally...
Poster/2010: Systematic and robust design of photonic crystal waveguides by topology optimization
Fengwen Wang1, Jakob S. Jensen1, Ole Sigmund1
1Department of Mechanical Engineering, Technical University of Denmark,Nils Koppels Allé, Building 404, 2800 Kgs. Lyngby, Denmark
Abstract: A robust topology optimization method is presented to consider manufacturing uncertainties in tailoring dispersion properties of photonic crystal waveguides. The under, normal and over-etching scenarios...
Poster/2011: Comparison between different dispersion engineering methods in slow light photonic crystal waveguides
Fengwen Wang1, Jakob S. Jensen1, Ole Sigmund1
1Department of Mechanical Engineering, Technical University of Denmark
Abstract: This paper compares the performance of different dispersion engineering methods in slow light photonic crystal waveguides, i.e., geometrical parameter optimization and topology optimization. In both...
Poster/2011: Topology optimization of ultra-fast nano-photonic switches
Yuriy Elesin1, Boyan Lazarov1, Jakob Jensen1, Ole Sigmund1
1Department of Mechanical Engineering, Technical University of Denmark, Nils Koppels Alle 404, DK 2800 Kongens Lyngby, Denmark
Abstract: The aim of this paper is to demonstrate 1D switch designs obtained by topology optimization which show better performance than the designs considered in...
