Title: Innovations of Janet E Townsend

Introduction

Janet E Townsend is a notable inventor based in Hamble, GB. She has made significant contributions to the field of optical technology, holding two patents that showcase her innovative spirit and technical expertise.

Latest Patents

Her latest patents include the "Sensitized Erbium Fiber Optical Amplifier and Source." This invention involves an optical fiber designed for amplifying or sourcing a light signal in a single transverse mode. The fiber comprises a host glass doped with erbium (Er) and a sensitizer such as ytterbium (Yb) or iron (Fe). The host glass is preferably doped silicic glass, such as phosphate or borate doped. Electrical energy is provided to diode lasers that pump the Nd laser rod, which in turn pumps the fiber. This configuration allows for high energy transfer from the diodes to the Nd laser rod, enabling high pumping powers to be coupled into the single-mode co-doped fiber. The amplifier provides power and small signal gains comparable to the best observed, while requiring only conventional and readily available diode-based pump sources.
