High-speed, surface-incident optical modulators arranged in two-dimensional arrays are promising for highly parallel optical interconnects, communication, sensing, and computing. Among various approaches, nonlocal metasurface resonators embedded with organic electro-optic (OEO) materials provide an attractive platform to achieve high-speed and efficient modulation. However, most previously demonstrated designs assumed normal-incidence optical beams, restricting their applications. Here, we fabricate a novel resonator that exploits a high-Q slow-light mode to sustain strong resonance under oblique incidence and experimentally confirm a resonance at desired oblique incidence.
