Dear All,

Currently I am doing a bit of research on anodic bonding of glass to
silicon.
I would like to know the following:
*       Is there, in general, a refractive index change due to the migration
of the alkali cations?
*       If so, what does the index profile look like?
*       What is the order of magnitude of the change?

Thank you in advance,

Gilbert Schuurman
