Title: The Innovative Contributions of Frank Sobel
Introduction: Frank Sobel, located in Rixheim, France, is a distinguished inventor with three patents to his name. His work primarily focuses on advanced optoelectronic and waveguide technologies, showcasing his commitment to innovation and development in these fields.
Latest Patents: One of Sobel's latest innovations is the "Concealed Optoelectronic Module." This module features a reflectance member designed to mitigate or eliminate fan-out field-of-view overlap, enabling a concealed appearance or minimal visual impact compared to the host device. The reflectance member may be implemented as a series of through holes or as a contiguous spin-coated polymeric coating. It has the capability to be diffusively reflective to the same specific wavelengths as the device it integrates with.
Another significant patent is the "Method for Manufacturing Waveguide Structures on Wafer-Level and Corresponding Waveguide Structures." This invention allows for the fabrication of waveguide structures on a wafer scale, consisting of a holding structure with two waveguides, each equipped with a core and two end faces. The separation structure within the holding structure ensures optical separation between the waveguides, enhancing functional capabilities. The manufacturing method involves shaping replication material using tool structures, hardening it, and then removing the tool structures, which yields multiple waveguide structures.
Career Highlights: Throughout his career, Frank Sobel has been associated with several prominent companies. He has worked with Heptagon Micro Optics Pte. Ltd. and Ams Sensors Singapore Pte. Ltd., where he has contributed his expertise in optoelectronics and waveguide technology.
Collaborations: Frank has also collaborated with industry professionals, including Jens Geiger and Simon Gubser, further enriching his innovative endeavors and expanding his contributions to the field.
Conclusion: Frank Sobel stands out as a notable inventor whose innovative patents in optoelectronics and waveguides illustrate his dedication to advancing technology. His work continues to influence the industry, and his collaborations reflect a strong commitment to innovation and improvement in engineering practices.
