tidy3d.components.source.Pulse

class Pulse

Bases: SourceTime, ABC

A source time that ramps up with some fwidth and oscillates at freq0.

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).
