Latest Patents

William L Barnes holds a patent for a "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 consists of a host glass doped with erbium (Er) and a sensitizer such as ytterbium (Yb) or iron (Fe). The preferred host glass is doped silicic glass, which can include phosphate or borate doping. The invention utilizes diode lasers to provide electrical energy that pumps a Nd laser rod, which subsequently 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 achieves power and small signal gains that are comparable to the best observed, while only requiring conventional and readily available diode-based pump sources.
