RESEARCH

I have reached topological photonics through experimental studies of linear and nonlinear optical responses of low-dimensional semiconductors, photonic crystals (polaritic crystals and plasmonic crystals) with resonant structures, and metamaterials.

I will clarify interesting topological physics by examining the transition from topologically trivial to nontrivial states.
