Title: Zhimin Cai: Innovator in Optical Fiber Technology
Introduction
Zhimin Cai is a prominent inventor based in Nanchang, China. He has made significant contributions to the field of optical fiber technology, holding a total of 2 patents. His work focuses on the development of few-mode optical fibers, which have important applications in telecommunications and data transmission.
Latest Patents
Zhimin Cai's latest patents include innovative designs for few-mode optical fibers. One of his patents describes a fiber with a core that has a refractive index of n1, surrounded by a downward-concave cladding layer with a refractive index of n2. This is further surrounded by a first upward-convex cladding layer with a refractive index of n3, and a second upward-convex cladding layer with a refractive index of n4. An outer layer with a refractive index of n5 completes the structure. The refractive indexes satisfy the condition n > n3 > n > n > n. This design allows for non-single mode operation in a direct waveguide state, achieving equivalent single-mode transmission when bent at a specific radius. Another patent also focuses on few-mode optical fibers, detailing a core enclosed by a cladding that includes multiple layers designed to enhance performance.
