Latest Patents

Siegfried Pongratz holds a patent for an "Optical planar wavelength selective filter and method of manufacture." This invention involves the creation of an optical planar wavelength selective filter formed on a printed circuit substrate. The design utilizes low optical loss polymers to create a layered structure that includes waveguides and free travel zones. A strategically placed diffraction grating on the substrate allows light from one waveguide to be diffracted, enabling it to exit the free travel zone and pass through other waveguides. The low optical loss polymer is a reaction product of the hydrolysis and polycondensation reaction of organically functionalized alkoxysilanes. With the appropriate grating, this apparatus can function as an optical triplexer at frequencies of 1310, 1490, and 1550 nanometers.
