Abstract(in Japanese) (See Japanese page)
Abstract(in English) We analyze the noise characteristics of an optical transmission system repeated by two-mode phase-sensitive optical parametric amplifiers, in which the signal and idler waves are not degenerated. For the first time, we derive a closed-form expression for the accumulated noise using the quantum-mechanical Langevin-equation approach. The derived noise formula enables us to calculate the deterioration of the noise figure due to the internal loss of the amplifier and noise characteristics of the optical-amplifier chain.
