Title: **John Irven: A Pioneer in Optical Fiber Technology**
Introduction
John Irven, an accomplished inventor based in Stansted, Great Britain, has made significant contributions to the field of optical fiber technology. With a remarkable portfolio of 10 patents, Irven's innovative work has paved the way for advancements in telecommunications and data transmission.
Latest Patents
Among John Irven's latest patents are two noteworthy inventions that demonstrate his expertise in optical fiber preform manufacture. The first patent details a process where a rod of silica is inserted into a substrate tube, which is lined with a layer of material that has a refractive index lower than that of silica. This configuration allows for the assembly of the rod and tube to be drawn into fiber or fused together to create a solid cross-section optical fiber preform.
The second patent describes a method for making solid preforms and the optical fibers drawn from them. This inventive process involves forming an optical glass fiber from an inner layer of germania doped glass, placed within the bore of an outer cladding tube made of silica. The assembly is rotated while heated, collapsing the bore to form an optical fiber preform, which is drawn into fiber in a subsequent operation. Irven's meticulous approach, including the deposition of germania under hydrogen-free conditions and appropriate heat treatment, ensures the preservation of germania while achieving a graded transition of the refractive index.
