Title: Engelbert Hartl: Innovator in Fiber Optics
Introduction
Engelbert Hartl is a notable inventor based in Munich, Germany. He has made significant contributions to the field of fiber optics, holding a total of five patents. His innovative work has advanced the technology used in optical devices, showcasing his expertise and creativity.
Latest Patents
One of Hartl's latest patents is for a fiber-optic depolarizer. This invention involves a process for manufacturing a fiber optic depolarizer that utilizes two optical fiber sections. These sections are designed to obtain the polarization planes of light and are connected in such a way that their principal axes enclose an angle of 45 degrees. An optical fiber piece that does not obtain polarization is inserted between these sections, ensuring that the principal axis orientations are adjusted correctly. This design allows for effective manipulation of light polarization.
Another significant patent by Hartl is for protective cladding for a mono-mode directional coupler. This protective cladding is made from at least two incoming and outgoing fiber optic waveguides that are fused along a coupling segment. The cladding consists of open parts that can be connected to form a tube-shaped structure. Importantly, the material of the cladding parts matches the coefficient of expansion of the waveguide material, preventing mechanical tensions during temperature changes.
