Chiral semiconductor metasurfaces are known to demonstrate a giant optical activity, highly efficient circularly polarized light emissivity and routing. In my talk I plan to focus on the properties of Fano resonances in chiral metasurfaces, responsible for these important properties. Two examples of photonic structures will be considered: a circularly polarized laser based on a planar semiconductor microcavity with chirally modulated upper mirror, and a semiconductor bi-metasurface for vertical routing of spin-polarized quantum dots' emission.
