Inverse-Design in Large Photonic Gratings Enabling Efficient Photonic-to-Free-Space Mode Coupling

A. Yulaev¹, D. A. Westly², Vladimir A. Aksyuk²
¹Department of Chemistry and Biochemistry, University of Maryland, College Park, MD, USA
²PML, National Institute of Standards and Technology, Gaithersburg, MD, USA

Realization of an efficient coupling between photonic sub-micrometer size modes and hundred micrometer wide free-space beams remains a main engineering hurdle to a wider acceptance of miniaturized chip-scale atomic and bio systems. The major obstacle comes from a gigantic mode mismatch ... En savoir plus

Thermal Battery Cell Modeling in a Spirally-Wound Geometry
