We prepare a superposition of a radial (or azimuthal) vector beam and a uniformly linearly polarized Gaussian beam; by varying the amplitudes of the two fields, we control the formation of pairs of these singular points and their spatial separation. We complete this study by applying the same ...
Recently it has been shown that one can convert a vector beam in frequency while retaining the polarisation structure, but changing wavelength207,208,209, for faithful vectorial wavelength control. A recent development is the use of structured matter for non-linear control of structured light. ...

This disclosure relates generally to micro-light emitting diodes (micro-LEDs). More specifically, and without limitation, disclosed herein are techniques for improving the beam profiles of light beams extracted from a micro-LED array and the light extraction efficiency for emitted light within a small...
The main idea is that in addition to gravity a new interaction between visible and dark sector can be mediated by a new sub-GeV vector or scalar boson, as a review of the current and projected limits of LDM and other New Physics, see e.g. Refs. [7], [8], [9], [10], [11]....
In addition, although we only show 12 cylindrically symmetric vector beams, the actual number is much larger than this, which is mainly limited by the resolution of the SLM. If the resolution region of the SLM is idealized, infinite vector beams can be generated. Section 2 introduces the ...
3.3. Phase Optimization to Enhance the Absolute Value of the Focus Poynting Vector In addition, it is often of interest to investigate the flow of light described by the Poynting vector and how it can be increased by the phase modulation of the incident beam. As seen in Figure 5, a scatte...
