The evolution of picocavities and plasmonic nanogaps is revolutionizing light confinement, enabling atom-level control in ...

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 ...

In 1873, Ernst Abbe proposed the famous diffraction limit theory, stating that the resolution of an optical system is limited by the light wavelength and numerical aperture. For a long time, the ...

Toward the end of the 19th century, Abbe and Rayleigh formulated the principles of optical diffraction that limits the resolution of optical instruments in the far-field where the distance between the ...
