The Spontaneous Cascading Mechanism Behind Critical Phenomena in Self-Coupled Lasers
Jiaoqing Wang, Yael Kfir-Cohen, Chenni Xu +4
The basic physics of lasers is characterized by a second-order continuous phase transition at the critical lasing threshold. Nevertheless, laser bistability with abrupt transitions…

Black hole optical analogue: photon sphere microlasers
Chenni Xu, Aswathy Sundaresan, Nazire-Begüm Kazkal +7
The bell-like ringdown of the gravitational field in the last stage of the merging of massive black holes is now routinely detected on earth by the last generation of gravitational…

Exploring non-Euclidean photonics: Pseudosphere microlaser
H. Girin, S. Bittner, X. Checoury +8
Classical and wave properties of microlasers with the shape of a truncated pseudosphere are investigated through experiments and numerical simulations. These pseudosphere microlase…
