Latest Patents
Joseph D. Evankow holds a patent for a "High power, high gain, low noise, two-stage optical amplifier." This invention achieves high output power, high gain, and low noise, making it suitable for use as a repeater in long-haul lightwave communication systems. The design employs a first amplifying stage with a signal gain that is sufficiently small to prevent self-saturation by amplified stimulated emission (ASE). By utilizing counter-propagating pump light, the invention maximizes inversion in the first stage amplifying medium. The use of Erbium-Doped Fiber Amplifiers (EDFAs) in both stages further enhances performance, ensuring nearly complete inversion and improved noise figures.
