Abstract
A low resistivity hybrid organic-inorganic material may include a proportion of charge traps including a trap element indirectly covalently bonded to a donor or acceptor element. The trap element may include tin. The donor or acceptor element may include indium and/or antimony. Bonding includes cross-linking via oxygen bonds and via organic cross-linkers. The material may be formed as a hybrid sol-gel. The material may have optical transmission and refractive index characteristics. The material may be formed as optical cladding proximal to a non-linear optical layer, and may form a portion of a second order nonlinear optical device. The second order nonlinear optical device may include and electro-optic device including an organic chromophore-loaded modulation layer.
