Noise figure measurements in phase-insensitive and phase-sensitive fiber parametric amplifier cascade
Paper in proceedings, 2010

By cascading two non-degenerate inline fiber-optic parametric amplifiers, we observe NF ~2dB (beating phase-insensitive quantum limit) at 16-dB gain for the second (phase-sensitive) stage after subtracting the excess noise from the first (phase-insensitive) stage.
