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: 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 recent overview of recent advancements in these emerging fields, with emphasis on photonic NH platforms, exceptional point dynamics, and the very promising interplay between non-Hermiticity and topological physics can be found in this paper.

TL;DR: In this article, a nonmagnetic topological insulator laser exhibiting topologically-protected transport is presented, which gives rise to single mode lasing, robustness against fabrication defects, and higher slope efficiencies compared to its trivial counterpart.

TL;DR: A unidirectional single-moded parity-time symmetric laser is shown by incorporating active S-bend structures with opposite chirality in the respective ring resonators by Measure the extinction ratio between the CW and CCW modes in a single ring resonator in the presence of an S- bend waveguide and experimentally investigate the uniddirectional emission in PT-symmetric systems below and above the exceptional point.
