Fisher-information retention under local driving in non-Hermitian feed-forward chains
Qingrui Bai, Zhichao Li, Junlong Kou
When local drive hardware is installed before a sensing task is revealed, directional non-Hermitian buildup creates a tradeoff between targeted preparation and spatial coverage. We…
Low-threshold vortex lasing in three-dimensional cavities via flatband bound states in the continuum
Zi-Xin Zhou, Weimin Wang, Huijie Li +2
Bound states in the continuum (BICs) offer a robust route toward high-Q resonators and topological structured-light generation. While optically pumped BIC lasers have advanced sign…
Multifunctional imaging enabled by optical bound states in the continuum with broken symmetry
Jiale Chen, Zhao-Xian Chen, Jun-Long Kou +1
For photonic crystal slab (PCS) structures, bound states in the continuum (BICs) and circularly polarized states (dubbed C-points) are important topological polarization singularit…
Platform for enhanced light-graphene interaction length and miniaturizing fiber stereo-devices
Fei Xu, Jun-long Kou, Jin-hui Chen +2
Sufficient light-matter interactions are important for waveguide-coupled graphene optoelectronic devices. Using a microfiber-based lab-on-a-rod technique, we present a platform for…
