On the Cover

Experimental images of optical-beam profiles: in (a) the beam carries l=1 orbital angular momentum (showing a characteristic doughnut profile), while (b) is an l=0 reference beam. Frames (c)-(f) show the interference between these beams when a dynamical phase is added to (b), and (g)-(f) show the interference when a geometric phase is added to (a).
