摘要
En 中文
Efficient, low-power, and highly integrated optoelectronic devices remain a critical yet challenging goal. Here, we introduce a multipoint Kerker effect membrane metasurface that merges Kerker's condition with quasi-bound states in the continuum (q-BICs). By engineering dual-mode dispersion, we achieve a high-efficiency beam deflector, simultaneously realizing robust parameter tolerance and narrow-linewidth resonances-two typically conflicting properties. Our experiment demonstrates an absolute beam deflection efficiency exceeding 92%, with exceptional spectral and spatial selectivity, including a 4-gigahertz linewidth, a 2.8 degrees divergence angle, and a quality factor of 114. Moreover, it enables 94% transmission intensity modulation under an ultralow continuous wave pump intensity of 0.5 W/cm2. These results establish the Kerker effect framework as a scalable and energy-efficient photonic platform, offering a powerful route toward integrable optoelectronic systems for next-generation wireless communication and LiDAR.
