tidy3d.ContinuousWave

class ContinuousWave

Bases: Pulse

Source time dependence that ramps up to continuous oscillation and holds until end of simulation.

Parameters:

• amplitude (Attribute: amplitude) –

  Type	NonNegativeFloat
  Default	= 1.0
  Description	Real-valued maximum amplitude of the time dependence.

• phase (Attribute: phase) –

  Type	float
  Default	= 0.0
  Units	rad
  Description	Phase shift of the time dependence.

• freq0 (Attribute: freq0) –

  Type	PositiveFloat
  Default
  Units	Hz
  Description	Central frequency of the pulse.

• fwidth (Attribute: fwidth) –

  Type	PositiveFloat
  Default
  Units	Hz
  Description	Standard deviation of the frequency content of the pulse.

• offset (Attribute: offset) –

  Type	ConstrainedFloatValue
  Default	= 5.0
  Description	Time delay of the maximum value of the pulse in units of 1 / (2pi * fwidth).

Note

Field decay will not occur, so the simulation will run for the full run_time. Also, source normalization of frequency-domain monitors is not meaningful.

Example

>>> cw = ContinuousWave(freq0=200e12, fwidth=20e12)
