New technique uses optical orbital angular momentum lattice to enhance information storage capacity
In the realm of optical holography, the conventional limitations of polarization, wavelength, and incident angle are giving way to a new era of possibilities. A breakthrough technique known as optical orbital angular momentum (OAM) multiplexing has emerged, offering a plethora of unique mode channels for data storage, 3D printing, artificial intelligence, and optical tweezers. Yet, there's a hunger for more storage capacity, which propels ongoing research.
