Fiberoptic amplifier system with noise figure reduction

摘要: A fiberoptic amplifier system having an optical amplifier, which receives input signal and generates amplified spontaneous emission noise, a variable polarization beam splitter, the noise from amplifier. The (ASE) is broadband with random state in rare earth-doped fiber In semiconductor laser diode ASE partially polarized depending upon waveguide structure of diode. figure reduction configuration, splitter responsive to split one-half away remaining into first port passes output port. This significantly reduces system.
