Abstract
We develop a new approach based on quasi-BICs to develop chiral metasurfaces exhibiting nonlinear circular dichroism (up to 99.9%) and high conversion efficiency (10(-2) W-2). Tuning mode interference allows selective linear and nonlinear circular dichroism. (c) 2021TheAuthor(s)File in questo prodotto:
