Title: The Innovations of Charles W. Haggans
Introduction
Charles W. Haggans is an accomplished inventor based in Woodbury, MN (US). He holds a total of 3 patents that showcase his contributions to the field of optical fiber technology. His work has significantly advanced the capabilities of optical fibers, making them more efficient and effective for various applications.
Latest Patents
Haggans' latest patents include groundbreaking inventions such as the Boron-doped optical fiber. This single-mode optical fiber features a core made of silica, which changes its refractivity upon exposure to actinic radiation of a predetermined wavelength. The cladding surrounding the core also consists of silica and has a different refractivity that similarly changes under the same conditions. The innovative aspect of this design is the inclusion of boron in either the core or cladding, ensuring that both components change their refractivity by substantially the same amount when exposed to actinic radiation.
Another notable patent is the Waveguide narrowband rejection filter. This optical fiber filter comprises a length of single-mode fiber designed for a specific operating wavelength. The design may include various configurations, such as a depressed inner clad fiber or a photosensitive matched inner clad fiber. The core and cladding are meticulously engineered to allow for the existence of specific modes, enhancing the filter's performance and efficiency.
