From: Simultaneous demultiplexing and steering of multiple orbital angular momentum modes
Measured intensity profiles.
(a,b) OAM−6 and OAM−9 demultiplexing with conventional fork phase mask and single incident OAM mode. (c,d) OAM−6 and OAM−9 demultiplexing with specially designed two-mode complex phase mask and single incident OAM mode. (e) A Gaussian beam incident onto the two-mode complex phase mask. (f) Two OAM modes incident onto the two-mode complex phase mask (simultaneous demultiplexing of two OAM modes accompanied by beam steering).
