Dirac photonic crystal
摘要
Abstract
Dirac Fermion,as one of the basic particles in the particle physics,nowadays have been widely used to describe the electronic states with the behavior of Dirac fermion in the topological electronics.These exotic electronic states are called Dirac point,which exhibited as a linear crossing point in the band structure.Usually Dirac point is the topological phase transition point and thus viewed as the mother state of various topological states.As an analogue of topological electronics,topological photonics,also attracted a great deal of interest due to its potential application.One of the key topic in topological photonics is to realize photonic bands with Dirac point.In this review,we briefly introduce the progress of Dirac point in the photonic system and focus on the realization method of Dirac point in photonic crystal by take advantage of lattice symmetry.We also discuss Weyl point in the photonic crystal as an extension of the Dirac point.关键词
