Title: The Innovations of Masaki Wada
Introduction
Masaki Wada is a prominent inventor based in Tsukuba, Japan. He has made significant contributions to the field of optical technology, holding a total of 12 patents. His work focuses on advancing optical fiber technology and improving transmission systems.
Latest Patents
Wada's latest patents include a multi-core optical fiber and a design method. The objective of this invention is to provide a multi-core configuration that allows for random mode coupling with arbitrary core refractive indices. This multi-core optical fiber features two or more core regions arranged within a clad region, with a minimum core interval smaller than the refractive index of the cores. The configuration ensures that only one propagation mode is present, while the core configuration and interval are adjusted to maintain an inter-mode coupling coefficient between adjacent cores within a specified range.
Another notable patent is an optical transmission system designed to easily control transmission capacity and optical signal quality, even when a MIMO equalizer is utilized. This system includes an N×M MIMO equalizer and receivers equal in number to the spatial multiplexing order of the optical fiber. By adjusting the number of signal beams transmitted through the optical fiber, the system can modify both transmission capacity and signal quality after the transmission line has been constructed.
