WebApr 12, 2024 · Aksyuk and his team demonstrated that a single photonic chip did the work of 36 optical components, simultaneously controlling the direction, focus, and polarization (the plane in which a light wave vibrates as it travels) of 12 laser beams divided among four distinct wavelengths. 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.
