Quantum noise limits on frequency and timing for optical pulses in a linear high-gain amplifier

Frequency and timing noise added in a linear optical amplifier of gain G grows as (G-1)/G. Provided that the pulse is initially in a coherent state, the output frequency and timing noise cannot exceed twice the input value. It is also shown that, in a transmission line with zero net gain and loss, t...

Description
Summary:Frequency and timing noise added in a linear optical amplifier of gain G grows as (G-1)/G. Provided that the pulse is initially in a coherent state, the output frequency and timing noise cannot exceed twice the input value. It is also shown that, in a transmission line with zero net gain and loss, the frequency and timing noise added in the lossy medium is equal to or larger than the noise added in the amplifier.
