near-zero-index nonlinear nanophotonics

exploring the exotic physical and optical phenomena

Photonic media with near-zero refractive index exhibits various extraordinary linear and nonlinear properties (Wu et al., 2021). Our studies can be sorted into four categories, namely,

fabrication: fabrication methods, protocols, and for special needs (e.g., (Huang et al., 2023; Wu et al., 2021)).
integration: prerequisite studies, design references, and hybrid integration (e.g., (Wu* et al., 2024; Sha et al., 2022)).
new phenomena: new linear and nonlinear phenomena that has great potential (e.g., (Wu* et al., 2024; Wu† et al., 2022; Wu et al., 2021)).
applications: nano- and integrated devices: useful for photonic computing, telecommunications, optical signal processing, etc (e.g., (Xie et al., 2020; Sha et al., 2022; Xie et al., 2022; Sha et al., 2021)).

Near-zero-index photonic media: fabrication, prerequisite studies, new phenomena, and applications.

We also aim to develop and introduce new techniques (Wu et al., 2021; Wang et al., 2021; Huang et al., 2022) in a multi- and inter-disciplinary way, and are active on theories and simulations (Wu et al., 2021; Wu et al., 2020).
