finesse.detectors.quantum_noise_detector.QuantumNoiseDetector

Overview

class finesse.detectors.quantum_noise_detector.QuantumNoiseDetector(name, node, nsr=False, sources=None, exclude_sources=None)

Bases: finesse.detectors.general.Detector, finesse.detectors.general.NoiseDetector

Represents a quantum noise detector with no RF demodulations.

It calculates the amplitude spectral density of the photocurrent noise of a photodiode output demodulated at the signal frequency.

Parameters

name : str

Name of newly created quantum noise detector.

node : Node

Node to read output from.

nsr : bool, optional

If true, calculate the noise-to-signal ratio rather than the absolute noise value.

sources : list of Connector, optional

If given, only detect quantum noise contributions from these components.

exclude_sources : list of Connector, optional

If given, don’t detect quantum noise contributions from any of these components, even if given in sources.
