finesse.components.modulator.Modulator

Overview

class finesse.components.modulator.Modulator(name, f, midx, order=1, mod_type=ModulatorType.pm, phase=0.0, positive_only=False)

Bases: Connector, FrequencyGenerator

Represents a modulator optical component with associated properties such as modulation frequency, index and order.

Parameters

namestr

Name of newly created modulator.

ffloat or Frequency, optional

Frequency of the modulation (in Hz) or Frequency object.

midxfloat

Modulation index, >= 0.

orderint, optional

Maximum order of modulations to produce. Must be 1 for amplitude modulation. Defaults to 1.

mod_typestr, optional

Modulation type, either ‘am’ (amplitude modulation) or ‘pm’ (phase modulation). Defaults to ‘pm’.

phasefloat, optional

Relative phase of modulation (in degrees). Defaults to 0.0.

positive_onlybool, optional

If True, only produce positive-frequency sidebands. Defaults to False.

Properties

Modulator.f	f : float or Frequency, optional Frequency of the modulation (in Hz) or Frequency object.
Modulator.order	order : int, optional Maximum order of modulations to produce.
