Topological photonics (2018, background): “gies to match the requirements are presently being actively explored using either magnetic elements (Bahari et al., 2017; Solnyshkov et al., 2018), optical nonlinearities (Khanikaev and Alù, 2015; Shi et al.”
Topological insulator laser: Theory (2018, background): “That system used magneto-optic effects, which are very weak at optical frequencies, and accordingly produced only a narrow topological band gap (40 pm) within which it was claimed that lasing occurred (33).”
Exceptional topology of non-Hermitian systems (2019, positive): “Providing another path toward new technology, topological lasers based on robust NH boundary and interface states have been discovered (Bahari et al. , 2017; St-Jean et al. , 2017; Bandres et al. , 2018; Harari et al. , 2018; Parto et al. , 2018; Zhao et al. , 2018).”
Active topological photonics (2019, background): “The first report on topological lasing in a 2D structure employed a magneto-optical 2D photonic crystal that breaks time-reversal symmetry (TRS), giving rise to a 1D chiral edge mode and resulting unidirectional lasing [30] (Figure 1F).”
Topological insulator laser: Experiments (2018, background): “In a following development, unidirectional edge-mode lasing was demonstrated in a topological photonic crystal configuration involving a yttrium iron garnet (YIG) substrate under the action of amagnetic field (32).”
Symmetry and Topology in Non-Hermitian Physics (2018, background): “, two-dimensional system without any symmetry [159–161]) [10,11,117,119,121,124,151,155], and the quantum spin Hall insulator (i.”
Roadmap on topological photonics (2022, background): “The first realization of lasing from such chiral edge modes was in a two-dimensional magneto-optical PhC under an external magnetic field [28] (figure 18(b)), soon followed by helical edge states of a two-dimensional lattice of microring resonators [30] (figure 18(c)).”
