Title: The Innovations of Stephen G. Grubb

Introduction

Stephen G. Grubb is a notable inventor based in DuPage, Illinois. He has made significant contributions to the field of optical technology, holding 2 patents that showcase his innovative spirit and technical expertise.

Latest Patents

One of his latest patents is 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. The system utilizes diode lasers to pump a 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.

Another significant patent is the "Optical Fiber Rare Earth Ion Upconversion Laser System." This invention outlines methods and apparatus for upconverting laser sources and amplifiers that utilize solid-state components. It achieves operation with a continuous or quasi-continuous single band infrared pumping source, using successive energy transfers between the pumping radiation and activator in the host of the lasant upconversion material under ordinary operating conditions.
