Abstract: A variable liquid crystal optical device for controlling the propagation of light has one or more transparent thin-film highly-resistive layer (HRL) coupled to a substrate and an electrode structure. The HRL has core layer and a cover or proximity layer, wherein the core layer material has a higher electrical conductivity and higher refractive index than the cover layer material; and wherein the core and cover layer materials have substantially the same free energies of formation of oxide. In this way, the electrode structure will be environmentally stable and responsive to an applied electrical current to generate a spatially non-uniform magnetic field.

Abstract: A MEMS (micro-electro-mechanical system) getter microdevice for controlling the ambient pressure inside the hermetic packages that enclose various types of MEMS, photonic, or optoelectronic devices. The getter microdevice revolves around a platform suspended at a height above a substrate, and which is supported by supporting legs having low thermal conductance. Layers are deposited on the platform, such layers including a properly patterned resistor element, a heat-spreading layer and, finally, a thin-film getter material. When an electrical current flows through it, the resistor element heats the thin-film getter material until it reaches its activation temperature. The getter material then absorbs the gas species that could be present in the hermetic package, such gas species possibly impairing the operation of the devices housed in the packages while reducing their lifetime.
