It was shown that deforming the honeycomb structure in a semiconductor photonic crystal in ways respecting C6v symmetry, one opens gaps at G point in the Dirac-type dispersion accompanied by a p-d band inversion, yielding a photonic analogue of quantum spin Hall effect [1]. In this talk, after a brief introduction on the basic notions of topology physics [2], I will discuss on recent research frontiers of semiconductor topological photonics and related fields [3-6].
