Title: The Innovations of Robert L Lingle
Introduction
Robert L Lingle is a prominent inventor based in Johns Creek, GA (US), known for his significant contributions to the field of optical fiber technology. With a total of 9 patents to his name, Lingle has made remarkable advancements that enhance the capabilities of fiber optics in various applications.
Latest Patents
One of Lingle's latest patents focuses on multiple LP-mode fiber designs for mode-division multiplexing. This invention describes a few-mode fiber that features a graded-index core and a surrounding cladding with a unique design. The cladding includes a ledge between the core and the trench, a down-doped trench adjacent to the ledge, and an undoped cladding region next to the trench. The refractive index profile of this fiber is specifically configured to support 9 or more LP modes, allowing for the transmission of spatially-multiplexed optical signals. The design ensures that undesired modes have effective indices that are close to or less than the cladding index, leading to leakage of these modes into the outer cladding. Furthermore, the index spacing between the desired mode with the lowest effective index and the leaky mode with the highest effective index is sufficiently large to prevent coupling between them.
Another notable patent by Lingle involves the manufacture of multi-mode optical fibers. This patent outlines a technique for designing and producing MMFs, with specific designs aimed at limiting the maximum variation in the dielectric constant weighted by the square of the wavelength. This innovation is particularly relevant for CWDM applications, showcasing Lingle's commitment to advancing optical fiber technology.
