Two-dimensional topological photonic systems

摘要: Abstract The topological phase of matter, originally proposed and first demonstrated in fermionic electronic systems, has drawn considerable research attention the past decades due to its robust transport edge states potential with respect future quantum information, communication, computation. Recently, searching for such a unique material bosonic systems become hot topic worldwide. So far, many models methods realizing them have been discovered photonic acoustic mechanical etc. These discoveries certainly yielded vast opportunities designing phases related properties domain. In this review, we focus on some representative employ underlying Dirac model analyze geometric phase. On basis these models, three common types two-dimensional are discussed: 1) Hall effect broken time-reversal symmetry; 2) insulator associated pseudo-time-reversal symmetry-protected mechanism; 3) time/space periodically modulated Floquet insulator. Finally, provide summary extension emerging field, including brief introduction Weyl point three-dimensional systems.
