| Abstract: | In this talk I will overview the recent advances of our group at Nanophotonics and Metamaterials
department at ITMO University in the field of topological photonics focusing on the following
topics:
1. Topological edge states in zigzag arrays. This includes their theoretical description and
experimental investigation in microwaves and optics, both on plasmonic and all-dielectric
platforms.
2. Time-reversal-invariant photonic topological systems in 1, 2 and 3 dimensions with the
topological states enabled by the bianisotropic response of the structure. Both theoretical description
and recent experimental results will be summarized.
3. Extraction of the topological invariant of a 2D metasurface from the measured far-field scattering
spectra. Such far-field spectroscopy of topological invariants provides an alternative paradigm to
the conventional near-field technique based on the edge state microscopy.
4. Interaction-induced topological edge states of bound photon pairs realized in the interacting
quantum regime: theoretical model and the proposed platform for experimental realization.
