TL;DR: This work demonstrates an all-dielectric magnet-free topological insulator laser, with desirable properties stemming from the topological transport of light in the laser cavity, and demonstrates higher slope efficiencies compared to those of the topologically trivial counterparts.

TL;DR: It is demonstrated that topological insulator lasers are theoretically possible and experimentally feasible and shown that the underlying topological properties lead to highly efficient lasers, robust to defects and disorder, with single-mode lasing even at conditions high above the laser threshold.

TL;DR: The experimental and theoretical results demonstrate that, in the presence of chiral-time symmetry, this non-Hermitian topological structure can experience phase transitions that are dictated by a complex geometric phase.

TL;DR: A new paradigm for topologically protected waveguiding in a complementary metal-oxide-semiconductor compatible platform is provided and the novel concept of isolating topological and trivial defect modes in the same system that can have important implications in topological physics is highlighted.

TL;DR: In this paper, the authors proposed a new scheme for ultra-sensitive laser gyroscopes that utilizes the physics of exceptional points and showed that the rotation-induced frequency splitting becomes proportional to the square root of the gyration speed, thus enhancing the sensitivity to low angular rotations by orders of magnitudes.
