Title: The Innovations of Anthony G Dunn
Introduction
Anthony G Dunn is a notable inventor based in Woodbridge, GB. He has made significant contributions to the field of optical fibres, holding a total of 3 patents. His work has advanced the technology used in optical communications, showcasing his expertise and innovative spirit.
Latest Patents
One of Dunn's latest patents involves graded index optical fibres. This invention focuses on a range of alkali metal borosilicate glass compositions that are modified by the addition of alkaline earth metal oxides. These materials are particularly suitable for producing graded index optical fibre using the double crucible method. The core glass from this range can be paired with a suitable cladding glass, which may either be another glass from the same range or an unmodified alkali metal borosilicate. This pairing allows for thermal diffusion in the nozzle of the double crucible, creating a composition gradient of alkaline earth metal oxide and, consequently, a refractive index gradient. The resulting fibres exhibit improved refractive index profiles, especially when the proportions of the oxides in the core and cladding glasses are optimized to avoid a simple ion-exchange mechanism. Dunn has successfully prepared fibres with numerical apertures of up to 0.268 and best loss values as low as 5.0 dB/km.
Another significant patent by Dunn pertains to glass optical fibres and the compositions suitable for use as core glass in high numerical aperture optical fibres. This invention encompasses a range of glass compositions that enhance the performance of optical fibres.
