Double-optical phase-transition in a three level Rydberg state in thermal Rubidium vapor
Lin Cheng, Kun Huang, Chunhui Shao +3
We report on the observation of electromagnetically induced transparency (EIT) with intrinsic phase transitions in a three-level ladder system within rubidium atomic vapor. The obs…

Spin-to-orbital angular momentum conversion in non-Hermitian photonic graphene
Zhaoyang Zhang, Pavel Kokhanchik, Zhenzhi Liu +7
Optical beams with orbital angular momentum (OAM) have numerous potential applications, but the means used for their generation often lack crucial on-demand control. In this work,…

Observation of nonreciprocal transverse localization of light
Shun Liang, Changchang Li, Wenqing Yu +7
Magnetic-free nonreciprocal optical devices that can prevent backscattering of signals are essential for integrated optical information processing. The achieved nonreciprocal behav…
