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 ...

Abstract: The current fundamental limits such as Shockley–Queisser, ergodic light-trapping limit, diffraction-limited imaging (Abbe diffraction limit), noise in detection, reciprocal optical systems ...

(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 ...
