Noise free amplification via the two-photon correlated spontaneous emission laser Academic Article uri icon


  • It is shown that a two-photon linear amplifier adds a phase-sensitive noise to the input signal. It is therefore possible to amplify a squeezed-signal quadrature with reduced added noise compared to standard phase-insensitive amplifiers. It is also shown that, under certain conditions on the input and the amplifier, it is possible to amplify a super-Poisson signal into a sub-Poisson output signal. 1988.
