Title: Michael R Keur: Innovator in Optical Amplification Technology
Introduction
Michael R Keur is a notable inventor based in Glenview, IL (US), recognized for his contributions to optical amplification technology. He holds a total of 4 patents, showcasing his innovative spirit and technical expertise in the field.
Latest Patents
Among his latest patents is the "Erbium and Erbium/Ytterbium cladding pumped hybrid optical amplifier." This invention provides an optical fiber amplifier apparatus and an optical signal amplification method. The amplifier apparatus includes an optical combiner that receives an input optical signal and a pump light beam, combining them for output. The first cladding pumped optical fiber, which contains Erbium as the only optically active dopant, pre-amplifies the input optical signal. A second cladding pumped optical fiber, which includes both Erbium and Ytterbium as optically active dopants, further amplifies the pre-amplified input optical signal to produce a desired amplified output. Another significant patent is the "Method and apparatus for suppressing relative intensity noise (RIN) and improving transmission signals." This invention involves generating at least two optical signals with differing wavelengths and combining them into a composite output signal, which reduces RIN compared to a single optical signal.
