Twisted light from topological chiral exceptional points in a nanolaser array
Kaiwen Ji, Melissa Hedir, Qi Zhong +3
We propose and experimentally demonstrate an orbital angular momentum (OAM) nanolaser array arranged in a ring geometry on an InP-based photonic crystal membrane. The device realiz…
Thermalization of quantum light induced by classical nonlinear wave dynamics
Fouad Chahrour, Şahin K. Ozdemir, Kurt Busch +2
Thermalization of isolated quantum systems is an intriguing phenomenon at the forefront of contemporary physics. In this work, we demonstrate that nonlinear multimode optical platf…
Exceptional Points and Lasing Thresholds: When Lower-Q Modes Win
Julius Kullig, Qi Zhong, Jan Wiersig +1
One of the most fundamental questions in laser physics is the following: Which mode of an optical cavity will reach the lasing threshold first when gain is applied? Intuitively, th…
Effect of imaginary gauge on wave transport in driven-dissipative systems
I. Komis, K. G. Makris, K. Busch +1
Wave transport in disordered media is a fundamental problem with direct implications in condensed matter, materials science, optics, atomic physics, and even biology. The majority…
Exceptional points-based optical amplifiers
Q. Zhong, S. K. Ozdemir, A. Eisfeld +2
The finite gain-bandwidth product is a fundamental figure of merit that restricts the operation of standard optical amplifiers. In microcavity setups, this becomes a serious proble…
