Latest Patents

Uwe Langbein holds a patent for a "Tapered waveguide for optical dispersion compensation." This optical device provides dispersion adjustment or compensation through resonant coupling between a first waveguide and a second waveguide with variable thickness and a significantly different index of refraction. The two waveguides are optically coupled about a lateral coupling surface. As light propagates down the waveguide, it transitions from one waveguide to the other at a predetermined position along the propagation axis, depending on the thickness of the second waveguide. Mode converters are utilized at both the input and output of the device to ensure more efficient operation. The first waveguide can be constructed from silica, while the second waveguide is made of silicon, resulting in a differential index of refraction of about 2. For effective dispersion compensation, the profile of the thickness of the second waveguide is designed so that shorter wavelengths are retarded relative to longer wavelengths, allowing for improved performance in optical communications.
