Abstract
A low resistivity hybrid optical cladding may be formed from a sol-gel doped with an inorganic salt such as lithium perchlorate. An electro-optic device may be formed by poling an organic chromophore-loaded modulation layer through at least one layer of the low resistivity hybrid optical cladding.
