Abstract
The disclosure provides an orbital angular momentum generating apparatus for polarization modulation of orbital angular momentum and method thereof, comprising a Gaussian light source module, a first orbital angular momentum modulation module, a second orbital angular momentum modulation module and a multiplexing module; when working, the Gaussian light source module generates a Gaussian light beam in any polarization state and enters the multiplexing module, which decomposes the Gaussian light beam into two component light components, both of which are respectively directed into the first or the second orbital angular momentum modulation module, the modulation module respectively performs orbital angular momentum modulation on the two modulated light components, which return to the multiplexing module, the multiplexing module superposes the two component lights, and finally the orbital angular momentum state or the superposed state is output.
