Want comprehensive? Go to the Mega DD thread on Reddit. It's my depository of all things LWLG. I have several dozen other technical papers on EOP that are not included in the Mega DD thread. I tried to keep it focused on LWLG, but the bottom section has a really good collection of general photonics resources and then a couple of the other EOP-related papers.
Here is the paper I was looking for on EOP and MRR's.
