Latest Patents

One of his latest patents is titled "Optical fiber transmission link having passive, directionally dependent attenuation." This invention aims to provide directionally dependent attenuation for an optical information transmission link using simple means without the need for active components. The design involves coupling two optical waveguides with different core diameters, where the second fiber's core diameter is at least six times greater than that of the first. This configuration allows for a significant attenuation of light signals in a predefined direction while minimizing attenuation in the reverse direction.

Another significant patent by Frank is the "Method for producing gradient index refraction index profiles in polymer optical fibers." This method utilizes ionizing radiation to create graded-index profiles in polymeric optical fibers, such as PMMA. By irradiating polymeric fibers or preforms with ionizing radiation of a specific wavelength and dose, while moving them past the radiation source, a uniform, radial graded-index profile is produced. This innovation enhances the transmission characteristics of optical signals in the fibers.
