Efficient GHz electro-optical modulation with a nonlocal lithium niobate metasurface in the linear and nonlinear regime - Nature Communications
A lithium niobate nonlocal metasurface with high-Q (~8000) resonances demonstrates efficient GHz-rate reflectivity modulation (~0.1) and one order of magnitude second harmonic modulation using sub-10V...
