Title: The Innovative Contributions of Sandra Davis
Introduction
Sandra Davis is a prominent inventor based in Ware, GB. She has made significant contributions to the field of optical technology, holding 2 patents that showcase her expertise and innovative spirit. Her work has had a considerable impact on the development of optical fibre technology.
Latest Patents
One of her latest patents is an optical fibre amplifier. This invention involves a length of optically amplifying fibre spliced between a pair of 2.times.2 tapered fused fibre couplers. Each coupler is constructed from a length of amplifier type profile fibre and a length of transmission type profile fibre. In this design, one of the two constituent fibres has been pre-stretched to match the propagation constants of the two fibres within the coupling region of that coupler.
Another notable patent is for polarization insensitive wavelength multiplexing 2.times.2 fibre couplers. This invention describes the manufacture of a wavelength multiplexing 2.times.2 tapered fused fiber coupler by progressive stretching. The birefringence of the coupler, resulting from the progressive stretching, is subsequently nulled-out by elastic twisting of the coupler. The progressive stretching is performed under temperature conditions that provide a profile in the coupling region of the coupler, ensuring that the coupling strength for one of the principal polarization planes remains substantially constant during the elastic twisting.
