OverviewOptical noise figureGeneralDefinitionNoise factor of cascaded devicesExternal links
The above describes noise in electrical systems. The optical noise figure is discussed in multiple sources. Electric sources generate noise with a power spectral density, or energy per mode, equal to kT, where k is the Boltzmann constant and T is the absolute temperature. One mode has two quadratures, i.e. the amplitudes of cos and sin oscillations of voltages, currents or fields. However, there is also noise in optical systems. In these, the sources have no fundamental noise. Instead the energy quantization
