A Comparative Test of Brillouin Amplification and Erbium-Doped Fiber Amplification for the Generation of Millimeter Waves With Low Phase Noise Properties

摘要

Measurements of phase noise of a 40-GHz carrier signal are presented. The carrier is generated by the amplification of harmonics due to stimulated Brillouin scattering. An analogy to a generation of millimeter waves by an erbium-doped fiber instead of the Brillouin amplifier is investigated and discussed. In our setup, both show a comparable behavior in respect to their noise characteristics.
