Researchers at Stanford have developed a dielectric diffraction grating that provides high (near-unity) diffraction efficiencies in an ultra-compact volume.
Stanford researchers patented a method to design, computationally optimize and fabricate efficient optical devices using semiconducting and dielectric nanostructures.
Stage of research
Researchers designed electro-optical gratings for fluorescence microscopy - a drop in to existing systems with no new lenses. Researchers demonstrate a 9x improvement on FOV using Olympus 10x/0.6NA WI immersion objective at 3.3 Hz.
