tidy3d.ContinuousWave#

class ContinuousWave[source]#

Bases: Pulse

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

Parameters:

  • amplitude (NonNegativeFloat = 1.0) – Real-valued maximum amplitude of the time dependence.

  • phase (float = 0.0) – [units = rad]. Phase shift of the time dependence.

  • freq0 (PositiveFloat) – [units = Hz]. Central frequency of the pulse.

  • fwidth (PositiveFloat) – [units = Hz]. Standard deviation of the frequency content of the pulse.

  • offset (ConstrainedFloatValue = 5.0) – 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)
