International Classification:

C02F 300

US Classification:

210605, 210613, 210620, 210626, 210239, 210607

Abstract:

A modular system for treating wastewater is designed having different phases. In an initial phase, plural tanks are provided, including at least one reactor and digester tank. In a subsequent phase, at least one of the tanks is converted into a different type of tank, and additional new tanks are provided to accommodate larger quantities of wastewater. In one embodiment, conversion of at least one of the tanks is accomplished by removing a temporary wall from a digester tank to create another reactor tank.

International Classification:

H01L029/84

US Classification:

257414, 257 21

Abstract:

A sub-assembly or package for a die in the receiving section of an optical transceiver includes a semiconductor sub-mount that is electrically connected to the die and a cap that is bonded to the sub-mount to hermetically seal the die in a cavity. The die can be flip-chip bonded to the sub-mount and can include a diffractive optical element fabricated on a back side of the die. Active circuitry such as an amplifier for an output signal from a photosensor one the die can be integrated into the sub-mount. For an OSA, a post can be attached to the package along a path of an optical signal to the photosensor. The post facilitates alignment of an optical fiber. A flexible or rigid circuit can be soldered to external terminals of the sub-mount.

US Classification:

257100, 257432, 257434, 385 88, 372101, 372107

Abstract:

A package for a surface-emitting laser encloses the die between a sub-mount and a cap. The sub-mount and the cap can be formed using wafer processing techniques that permit a wafer level packaging process which attaches multiple die to a sub-mount wafer, attaches caps either separated or as part of a cap wafer to the sub-mount wafer, and cuts the structure to separate individual packages. The cap includes a transparent plate that can be processed to incorporate an optical element such as a lens. An alignment post attached to the cap indicates the position of an optical signal from the laser and fits snugly into one end of a sleeve while an optical fiber connector fits into the other end.

US Classification:

385 88, 257 98, 257432, 257433, 372109, 385 33, 438106

Abstract:

An optoelectronic package or sub-assembly includes an edge-emitting laser and a reflector that directs a beam from the laser through a sub-mount. The sub-mount contains passive or active circuit elements that are electrically connected to the laser. The laser can be protected from the environment using either a cap in which the reflector is integrated or using an encapsulant encasing the laser. An alignment post that is sized to fit into a sleeve is mounted where the optical signal emerges from the sub-mount. Plugging the post into one end of the sleeve and inserting an optical fiber into the other end of the sleeve so that the optical fiber abuts the post will then align the optical fiber to receive the optical signal.

US Classification:

372034000, 257098000

Abstract:

An optoelectronic device includes a submount and a lid. The submount includes a substrate and a lens and a laser above the substrate. The lid defines a cavity having a surface coated with a reflective material to form a 45 degree mirror. The mirror reflects a light from the laser to the lens and the light exits the optoelectronic device through the submount.
