In this Letter, we experimentally demonstrate nonlinear optical negative refraction in thin metallic nanostructures. We use a degenerate four-wave mixing (4WM) process to show efficient frequency ...
Scientists have unveiled a compact optical sensor using differential guided-mode resonance that achieves record sensitivity in detecting refractive index changes. Their sensor opens new possibilities ...
