Patent Issued for Optoelectronic Component

September 3, 2014



By a News Reporter-Staff News Editor at Electronics Newsweekly -- OSRAM Opto Semiconductors GmbH (DE) has been issued patent number 8811448, according to news reporting originating out of Alexandria, Virginia, by VerticalNews editors.

The patent's inventor is Illek, Stefan (Donaustauf, DE).

This patent was filed on August 31, 2009 and was published online on August 19, 2014.

From the background information supplied by the inventors, news correspondents obtained the following quote: "US 2002/0001328 discloses an optoelectronic component. However, it could be helpful to provide an optoelectronic component which can be produced in a particularly simple manner, can be a particularly compact laser light source, and can be produced in a simplified production method."

Supplementing the background information on this patent, VerticalNews reporters also obtained the inventor's summary information for this patent: "I provide an optoelectronic component including an optical pump device including a first radiation-generating layer and a first radiation exit area at a top side of the pump device, wherein electromagnetic radiation generated during operation of the pump device is coupled out from the pump device through the first radiation exit area transversely and at least in part non-perpendicularly with respect to the first radiation-generating layer, and a surface emitting semiconductor laser chip including a reflective layer sequence including a Bragg mirror, and a second radiation-generating layer, wherein the surface emitting semiconductor laser chip is fixed to the top side of the pump device, and the reflective layer sequence is arranged between the first radiation exit area and the second radiation-generating layer.

"I also provide a method for producing a optoelectronic component including providing a multiplicity of pump devices present as an assemblage in a first wafer, wherein a first radiation exit area is provided at the top side of each pump device, providing a multiplicity of surface emitting semiconductor laser chips present as an assemblage in a second wafer, connecting first and second wafer such that top sides of the pump devices face a surface emitting semiconductor laser chips, and singulating the connected wafers to form individual optoelectronic components."
