Abstract: An optical signal amplification apparatus and a related optical communication device. The apparatus may include a pump light source, a combiner assembly, a doped optical fiber, and an optical filter. The pump light source may be configured to emit a pump beam. The combiner assembly is configured to combine a signal beam and the pump beam and couple a combined beam into the doped optical fiber. The doped optical fiber is configured to amplify the signal beam under excitation by the pump beam. The signal beam includes one or more single-wavelength signals. The optical filter is disposed between two ends of the doped optical fiber and configured to transmit the signal beam and filter out a first beam in the doped optical fiber. The first beam includes a beam of some wavelengths or all wavelengths generated by spontaneous emission in the doped optical fiber.

Abstract: Example optical amplification apparatus and example signal amplification methods are provided. One example optical amplification apparatus is connected to an optical fiber. The optical amplification apparatus includes a first pump laser and a first gain medium. The first pump laser is configured to emit first pump light. The first gain medium is configured to receive the first pump light and first multi-channel optical signals from the optical fiber; and perform gain amplification on the first multi-channel optical signals based on the first pump light, where the first pump light overlaps each of the first multi-channel optical signals in the first gain medium.
