Making Light Spin With a Gold Nanorod

AI-summarised brief · reviewed before publication

Researchers from Tokyo University of Science have developed a simpler method to control photon spin by striking a gold nanorod off-center with an electron beam, causing the surrounding light to rotate. This technique, demonstrated through experiments with an optical fiber, could enable more compact and efficient control of light in nanoscale devices, with potential applications in quantum communication and integrated photonic circuits. The method offers a more accessible approach to generating circularly polarized light.
