Generation of Optical Vortices by Linear Phase Ramps
Figure 8
(a) Simulated intensity distribution for linear array of inclined phase ramps with constant background. (b) Simulated interference patterns to check formation of optical vortices. (c) Simulated results for zero crossing of real and imaginary lines for linear array of inclined phase ramps with constant background. Green line represents real part and red line represents imaginary part of the wave function.
