Dear all,

Is there any way that the refractive index of the SU-8 be altered, i.e
during the baking/ curing stage? Some polymers do change their R.I's when
subject to heating at different temperatures. A slight change in the index
is an advantage. Usually, lower than 1%, prefably 0.4%. Is there anyone who
has done any study on the refractive index variation of the SU-8? Your kind
help is highly appreciated.
