Focusing light to a tighter spot
TLDR
In this article, a novel radially polarized instead of a linearly polarized light annulus was proposed to reduce the focal area of a high aperture lens, which achieved an even smaller focal area, which is determined by the contour of the intensity distribution at half the maximum value.About:

Metal wires for terahertz wave guiding
Kanglin Wang,Daniel M. Mittleman +1 more
TL;DR: It is shown how a simple waveguide, namely a bare metal wire, can be used to transport terahertz pulses with virtually no dispersion, low attenuation, and with remarkable structural simplicity.

Tip-enhanced Raman spectroscopy and microscopy on single dye molecules with 15 nm resolution.
Jens Steidtner,Bruno Pettinger +1 more
TL;DR: Because of the reduced photobleaching in UHV, the time frame for spectral acquisition is sufficiently extended to allow tip-enhanced Raman imaging of a single BCB molecule with a lateral resolution of 15 nm.

Optical stethoscopy: Image recording with resolution λ/20
TL;DR: In this paper, an extremely narrow aperture along a test object equipped with fine-line structures was used to demonstrate a resolving power of at least λ/20 which is to be compared with the values of λ 2.3 obtainable in conventional optical microscopy.

Interaction with the Absorber as the Mechanism of Radiation
TL;DR: In this paper, Niels Bohr pointed out that further advance into this region will require a still more extensive renunciation of features which we are accustomed to demand of the space time mode of description.

Theory of Nanometric Optical Tweezers
TL;DR: In this article, the authors proposed a method for optical trapping and alignment of dielectric particles in aqueous environments at the nanometer scale based on the highly enhanced electric field close to a laser-illuminated metal tip and the strong mechanical forces and torque associated with these fields.
