Abstract: A high purity aqueous solution of hydroxylamine product is prepared by treating an aqueous solution of hydroxylammonium salt with a base like ammonia at low temperatures. A novel process can be carried out by separating the ammonium salt side product from hydroxylamine with a low temperature filtration and a resin-exchange process. The concentration of the hydroxylamine product is further improved by a safe distillation process that produces a high purity and high concentration hydroxylamine product with reduced risks of explosion.

Abstract: An edge-coupled photodetector, especially a compound semiconductor edge-coupled photodetectors, has a light funnel integrated right in front of the coupling aperture for enhancing the optical coupling efficiency. The light funnel is formed utilizing either a wet etched, crystallographically defined semiconductor slope or a dry etched, resist-profile-defined semiconductor slope covered by the planarized dielectrics. The funnel internals can be partially or fully metallized for total mirror reflection. The lightwave entering the funnel and propagating along the optical axis converges through mirror reflection or total internal reflection. Through such an invention, the edge-coupled photodetector can have both high operation speed and high quantum efficiency with enlarged alignment tolerance.
