We present a calculation of quantum noise for parametric amplification in periodically inverted nonlinear media. An analytical expression is obtained for the noise figure of the amplifier. We show that such optical parametric amplifiers run in a phase-sensitive configuration can achieve noiseless amplification and squeezing, thus constituting a promising way for the integration of noiseless optical amplifiers in a communication line.

We describe some limitations of the noise performance of classical optical devices which are directly related to the Poissonian statistics associated with ordinary laser beams. We show that quantum optics, via optical parametric amplification, allows us to circumvent these limitations in order to realize certain noiseless optical functions such as amplification, duplication, detection and distribution of optical signals.
