Generation of Optical Vortices by Linear Phase Ramps
Figure 9
(a) Simulated intensity distribution for linear array for two oppositely inclined phase ramps with different tilt. (b) Simulated interference patterns to check formation of optical vortices. (c) Simulated results for zero crossing of real and imaginary for two oppositely inclined phase ramps with different tilt. In the figure green line represents real part and red line represents imaginary part of the wave function.
