Introduction

Walter Belardi is a notable inventor based in Southampton, GB. He has made significant contributions to the field of optical fibre technology, holding 2 patents that showcase his innovative approach to utilizing the Raman effect in optical devices.

Latest Patents

Belardi's latest patents include advancements in optical fibre-based devices that utilize the Raman effect. One of his inventions describes an optical fibre device that comprises a first optical source providing light at a first wavelength. This device employs a holey optical fibre that receives light from the source, allowing for optical gain or loss at a second wavelength through Raman scattering. For optical gain, the second wavelength is longer than the first, enabling the device to function as an amplifier or laser with optical feedback. Conversely, for optical loss, the second wavelength is shorter, allowing the device to serve as an optical modulator. The fibre can be made from pure silica or other materials to enhance its properties, such as gain spectrum and power handling capability.

Another patent focuses on the design of holey optical fibres. This invention features a structure with a holey fibre arranged within a holey outer support made of holey tubes encased in a thin-walled outer jacket. The holey fibre may have a solid core surrounded by a holey cladding with multiple rings of holes. This design allows for the production of robust, coated, and jacketed fibres with microstructured core features, utilizing existing fibre fabrication technology effectively.
