Creates an optical signal from an electrical signal. It models an ideal laser diode by transfering the electrical signal to an optical.
This class is usually used after the class pypho_signalsrc.
pypho_lasmod.__init__(glova, power, Df, teta)
Instantiation and parameter setting.
| Parameter | Type | Description |
|---|---|---|
glova |
instance | Global parameters |
power |
float | Mean signal power in dBm. |
Df |
float | Frequency deviation of the signal in GHz. Default value is 0 GHz. |
teta |
float | Rotation of the polarisation in rad. Default value is 0: Only optical signal power in X-polarisation. |
