Robust Design of Slow-Light Tapers in Periodic Waveguides
robust optimization PDE-constrained optimization shape optimization coupling taper
2015/7/9
This paper concerns the design of tapers for coupling power between uniform and slow-light periodic waveguides. New optimization methods are described for designing robust tapers, which not only perfo...
Robust Optimization of Adiabatic Tapers for Coupling to Slow-Light Photonic-Crystal Waveguides
Computational electromagnetic methods Optoelectronics Photonic crystal waveguides Photonic integrated circuits
