A planar optical device is formed on a substrate. The device comprises an array of waveguide cores which guide optical radiation. A cladding layer is formed contiguously with the array of waveguide cores to confine the optical radiation to the array of waveguide cores. At least one of the array of waveguide cores and cladding layer is an inorganic-organic hybrid material that comprises an extended matrix containing silicon and oxygen atoms with at least a fraction of the silicon atoms being directly bonded to substituted or unsubstituted hydrocarbon moieties. This material can be designed with an index of refraction between 1.4 and 1.55 and can be deposited rapidly to thicknesses of up to 40 microns. In accordance with another embodiment of the invention, a method for forming a planar optical device obviates the need for a lithographic process. Illustratively, a method for forming an array of cores comprises the steps of: (1) preparing a waveguide core composition precursor material comprising at least one silane and a source of hydrocarbon moiety, (2) partially hydrolyzing and polymerizing the waveguide core precursor material to form a waveguide core composition, (3) using a mold, forming an array of waveguide cores comprising the waveguide core composition, and (4) completing hydrolysis and polymerization of the waveguide core composition under conditions effective to form an inorganic-organic hybrid material that comprises an extended matrix containing silicon and oxygen atoms with at least a fraction of the silicon atoms being directly bonded to substituted or unsubstituted hydrocarbon moieties. A cladding layer is then deposited over the array of waveguide cores. The use of the mold to pattern the array of waveguide cores obviates the need for a lithographic process.

Inorganic semiconducting compounds, composites and compositions thereof, and related device structures.

The present invention relates to porous inorganic / organic homogenous copolymeric hybrid material materials, including particulates and monoliths, methods for their manufacture, and uses thereof, e.g., as chromatographic separations materials.

The invention discloses an inorganic / organic composite porous membrane, which comprises a porous base material and an active layer attached to the porous base material, wherein the active layer contains a mixture of inorganic granules and a bonding agent. In the inorganic / organic composite porous membrane, the defect of poor heat safety of the conventional polyolefin-base diaphragm is overcome by using the inorganic / organic composite porous membrane formed by the porous base material, the inorganic granules and the bonding agent; the inorganic / organic composite porous membrane has the high antioxidation, can prevent the diaphragm from being oxidized in a lithium battery of a high-voltage anode material system, has the absorption and infiltration capacity of electrolyte which is better than that of conventional polyolefin-base diaphragm, and can improve solve the problem of the absorption and infiltration of the electrolyte in the large-size lithium battery and the lithium precipitation of the battery effectively. Therefore, the inorganic / organic composite porous membrane can improve the performance and safety of an electrochemical device serving as the inorganic / organic composite porous membrane as the diaphragm. In addition, the invention also discloses a preparation method for the inorganic / organic composite porous membrane and the electrochemical device using the membrane.
