Overview
- class finesse.detectors.quantum_noise_detector.QuantumShotNoiseDetectorDemod2(name, *args, **kwargs)[source]¶
Bases:
Detector
Represents a quantum shot noise detector with 2 RF demodulations.
It calculates the amplitude spectral density of the photocurrent noise of a photodiode output demodulated at the signal frequency, considering only vacuum noise contributions (ignoring radiation pressure and squeezing effects).
- Parameters
- namestr
Name of newly created quantum shot noise detector.
- node
Node
Node to read output from.
- f1float
First demodulation frequency in Hz
- phase1float
First demodulation phase in degrees
- f2float
Second demodulation frequency in Hz
- phase2float
Second demodulation phase in degrees
- nsrbool, optional
If true, calculate the noise-to-signal ratio rather than the absolute noise value.
