Optical multistability in a compact microcavity enabled by near-exceptional coupling
Zhen Liu, Xuefan Yin, Andrey Bogdanov +5
Multistability -- the emergence of multiple stable states under identical conditions -- is a hallmark of nonlinear complexity and an enabling mechanism for multilevel optical memor…
Wave morphing and flat-top ground states in photonics systems driven by artificial gauge fields
Peishen Li, Xiaoyu Zhang, Feifan Wang +3
In quantum physics, classical optics, and many other wave systems, wave confinement in a potential well is associated with discrete oscillatory states, and the ground state is typi…
