Thank you, that was exactly the effect I was looking for. Any links handy? Fascinating stuff, this from an old microwave-digital guy.



Sure! Here's a research group in Glasgow that has a great site: http://www.physics.gla.ac.uk/Optics/play/photonOAM/

And here is the lab where I did my undergrad research (Colgate Univ.): http://departments.colgate.edu/physics/research/optics/oamgp...

happy to offer up my phd thesis as well: http://shel.tv/henry_thesis
