    摘要： The invention comprises ferroelectric vapor deposition targets and to methods of making ferroelectric vapor deposition targets. In one implementation, a ferroelectric physical vapor deposition target has a predominate grain size of less than or equal to 1.0 micron, and has a density of at least 95% of maximum theoretical density. In one implementation, a method of making a ferroelectric physical vapor deposition target includes positioning a prereacted ferroelectric powder within a hot press cavity. The prereacted ferroelectric powder predominately includes individual prereacted ferroelectric particles having a maximum straight linear dimension of less than or equal to about 100 nanometers. The prereacted ferroelectric powder is hot pressed within the cavity into a physical vapor deposition target of desired shape having a density of at least about 95% of maximum theoretical density and a predominate maximum grain size which is less than or equal to 1.0 micron. In one implementation, the prereacted ferroelectric powder is hot pressed within the cavity into a physical vapor deposition target of desired shape at a maximum pressing temperature which is at least 200null C. lower than would be required to produce a target of a first density of at least 85% of maximum theoretical density in hot pressing the same powder but having a predominate particle size maximum straight linear dimension of at least 1.0 micron at the same pressure and for the same amount of time, and a target density greater than the first density at the lower pressing temperature is achieved.

    摘要： An electro-optically deactivated transmissive material comprises a plurality of chemicals which are sufficient, in combination, to enable formation of an electro-optic material having an index of refraction that is responsive to an electric field. The chemicals are combined with a glassifier so as to form a transmissive material that is less responsive to the electric field than said electro-optic material. The deactivated material has substantially the same refractive index as the electro-optic material in the absence of an electric field. In a preferred embodiment, the deactivated material is arranged with active material to form an optical switch.
