Specialty doped glass products are used in various sectors including semiconductors, lens designs, laser power delivery systems, and scientific and medical applications. FiberCore quoted Charles De Luca, MD of FiberCore Jena AG, as saying that while the size of the order is “not material”, the placement of the order validates the process and the technology, and FiberCore expects further orders from this customer and others for fiber optic and other applications. In April 2003 FiberCore received its second patent from the USPTO for POVD, a technology that the company claims can lower the cost of manufacturing part or all of an optical fiber preform.
