Imagine light beams that twist and turn, carrying a unique form of momentum. Orbital angular momentum (OAM) light beams, with their distinctive donut-shaped intensity profiles and helical phase fronts, have revolutionized fields like astronomy, microscopy, and optical communications over the past two decades. From manipulating microscopic objects to boosting the capacity of fiber-optic networks, OAM is reshaping the future of light-based technologies.
OAM holds promise for revolutionizing optical communications. By encoding information onto the twist of the light beam, OAM offers a new dimension for data transmission, significantly expanding the bandwidth of fiber-optic networks. This innovative approach promises to unlock the potential for faster, more efficient, and high-capacity data transfer.
