    They pass both quadratures. For an optical amplifier it holds F o,IQ = n sp (1-1/G)+1/G ≥ 1. Quantity n sp (1-1/G) is the input-referred number of added noise photons per mode. F o,IQ and F pnf can easily be converted into each other. For large G it holds F o,IQ = F pnf /2 or, when expressed in dB, F o,IQ is 3 dB less than F pnf. The ideal F ...
