Abstract: High rate deposition methods comprise depositing a powder coating from a product flow. The product flow results from a chemical reaction within the flow. Some of the powder coatings consolidate under appropriate conditions into an optical coating. The substrate can have a first optical coating onto which the powder coating is placed. The resulting optical coating following consolidation can have a large index-of-refraction difference with the underlying first optical coating, high thickness and index-of-refraction uniformity across the substrate and high thickness and index-of-refraction uniformity between coatings formed on different substrates under equivalent conditions. In some embodiments, the deposition can result in a powder coating of at least about 100 nm in no more than about 30 minutes with a substrate having a surface area of at least about 25 square centimeters.

Abstract: Optical networks can comprise a branch structure with the de-multiplexing/multiplexing structure that operates to disperse a plurality of optical bands. Thus, the optical network comprises an optical network connection with a common optical channel, a plurality of de-multiplexed branch optical service connections and the de-multiplexing/multiplexing structure. In some embodiments, one optical band can be used to deliver input from a common channel to the branch node and the other optical band can carry output along the common channel from the branch node. The de-multiplexing/multiplexing element can be an arrayed waveguide grating. The AWG can have desirable architecture to efficiently provide the corresponding functions with respect to the two optical bands. Appropriate photodetectors and light sources can be associated with the AWG.

Abstract: Arrayed waveguide grating can have one or both slab waveguides with relatively sharply folded optical paths and a mirror that provides the folding of the path. The folded optical paths through the slab waveguides can result in a more compact geometry of the waveguides through the device as well as smaller slab waveguides such that the device can be formed with a significantly smaller overall footprint. Also, arrayed waveguide gratings that cooperate with pivotable mirrors can adjust light passage through the waveguide in response to temperature changes to provide for thermally compensated operation of the device. Thus, very compact planar lightwave circuits filters are described that provide thermally compensated operation.
