Title: Grant D Cunningham: Innovator in Optical Fiber Technology
Introduction
Grant D Cunningham is a notable inventor based in Painted Post, NY (US). He has made significant contributions to the field of optical fiber technology. His innovative work has led to the development of a unique optical fiber that enhances signal amplification.
Latest Patents
Cunningham holds a patent for the P-Si Er fiber profile. This optical fiber is designed for signal amplification and features a core doped with at least 15% phosphorus by weight, along with a rare earth ion that provides the necessary amplification of an optical signal. The fiber also includes a clad layer surrounding the core, which has an inner portion and an outer portion. The refractive index of the inner portion of the clad layer is lower than that at the outer radius of the core region. This design effectively confines electromagnetic radiation within a selected wavelength range to the core.
