What is the effect of ASE Noise Figure?

The Noise Figure of an amplifier is a key parameter that determines its performance. It is directly influenced by the Amplified Spontaneous Emission (ASE) power. An increase in ASE power results in an increase in the Noise Figure. This is because more pump power is required, resulting in larger ASE noise and other noises generated in the amplifier. If the input signal power to the amplifier decreases, the ASE competes more successfully with the signal for receiving gain. This leads to a decrease in the output Signal-to-Noise Ratio (SNR) and an increase in the Noise Figure.

How to Calculate Noise Figure given ASE Noise Power?

Noise Figure given ASE Noise Power calculator uses Noise Figure = 10*log10(ASE Noise Power/(Single Pass Gain*[hP]*Frequency Of Incident Light*Post Detection Bandwidth)) to calculate the Noise Figure, Noise Figure given ASE Noise Power is also referred to as the noise factor. These terms are used to indicate the degradation of the signal-to-noise ratio (SNR) caused by components in a signal chain. They are figures of merit used to evaluate the performance of an amplifier or a radio receiver, with lower values indicating better performance. Noise Figure is denoted by F_n symbol.
