Abstract: In the letter, we propose a holographic data storage method based on orbital angular momentum (OAM). In the proposed method, the OAM holography by discovering strong OAM selectivity in the ...

Abstract: We experimentally demonstrate the first record long-single-span MDM+WDM transmission of 3 orbital angular momentum (OAM) modes and 22 wavelength channels in 110-km large-core fiber without ...
