The emission control of standalone quantum sources has recently attracted the interest of the scientific community due to the growing technological capabilities for fabrication and on-demand positioning of these emitters. Here we report on simulation of silicon-oninsulator prismatic nanoantenna possessing resonantly induced bianisotropy that provides a strong dependence of its emission on the location of the quantum emitter inside the system. Obtained results could potentially be used in sensing, nanoscale light control, and quantum computing applications.
