A pioneering team from the Xi'an Institute of Optics and Precision Mechanics at the Chinese Academy of Sciences has introduced a novel nonlocal metasurface design, marking the first instance of strong coupling between quasi-guided modes (Q-GMs) and epsilon-near-zero (ENZ) modes. Through the implementation of periodic perturbations, the team successfully achieved the folding of the first Brillouin zone, enabling the creation of angle-tunable Q-GMs with high-quality factors. This groundbreaking achievement transcends the limitations of traditional Q-BIC in terms of wave vector and wavelength. The proposed design substantially amplifies nonlinear optical effects, opening up a new technological avenue for the development of nonlinear photonic devices that offer large-angle and multi-wavelength control. The research holds promising applications in diverse fields, including integrated photonics.
