Arbitrary vector beam encoding using single modulation for information security applications
IEEE Photonics Technology Letters, 2021•ieeexplore.ieee.org
Features of vector beam such as its spatial degree of freedom and intensity-based
measurements are useful in information encoding but often require a complex optical-setup.
In this letter, the concept of modulating a single-polarization component for encoding in
arbitrary vector field through a non-interferometric approach has been introduced. Utilizing
this concept, an efficient information security scheme has been demonstrated. The
experimental results verify the feasibility of a practical system.
