Latest Patents

Paul Hull holds a patent for an "Apparatus and method for channel monitoring in a hybrid distributed Raman/EDFA optical amplifier." This invention provides a hybrid Raman/EDFA optical amplifier that utilizes a first optical detector to generate a first electrical signal proportional to the combined optical power of the signal light and the leaked pump laser light. Additionally, a second optical detector generates a second electrical signal proportional to the power of the pump laser light. An electronic subtraction circuit processes these signals to produce a difference signal that reflects only the optical power of the signal light, making it insensitive to the power of the Raman pump laser light. This difference signal is crucial for the EDFA control circuit, which adjusts the operation of the EDFA based on changes in the input optical signal's power.
