(a) Working principle of metasurface displacement measurement can be understood as the detection of the power of different modes of the converted light. The incident irradiated on the metasurface and ...

Researchers built a silver-grooved chip that channels laser energy into nanometer-spaced peaks, beating the diffraction limit and aiding light-matter studies. (Nanowerk News) Physics is full of pesky ...

Researchers from the University of Science and Technology of China (USTC) have unveiled a planar optical device that ...

Near-field optics operates on the principle that when light interacts with objects smaller than its wavelength, it can produce an evanescent wave that decays exponentially with distance but provides ...
