The orbital angular momentum of light (OAM) is the component of angular momentum of a light beam that is dependent on the field spatial distribution, and not on the polarization. It can be further split into an internal and an external OAM. The internal OAM is an origin-independent angular momentum of a … See more A beam of light carries a linear momentum $${\displaystyle \mathbf {P} }$$, and hence it can be also attributed an external angular momentum $${\displaystyle \mathbf {L} _{e}=\mathbf {r} \times \mathbf {P} }$$. … See more Determining the spin angular momentum (SAM) of light is simple – SAM is related to the polarization state of the light: the AM is, per photon, in a left and right circularly polarized beam respectively. Thus the SAM can be measured by transforming the … See more In 2024, a letter published in the Monthly Notices of the Royal Astronomical Society presented evidence that OAM radio signals had been … See more • Angular momentum • Angular momentum of light • Orbital angular momentum of free electrons • Circular polarization • Hypergeometric-Gaussian modes See more Orbital angular momentum states with $${\displaystyle l=\pm 1}$$ occur naturally.

WebAn optical beam is said to be self-healing when, distorted by an obstacle, the beam corrects itself upon propagation. In this Letter we show, through experiments supported by numerical simulations, that Helico-conical optical beams self-heal. We observe the strong resilience of these beams with different types of obstructions, and relate this to the characteristics of …
