wg_length String

A struct defining the length of the thermal switch with the following fields: 

  • name: name of the "thermal switch length" parameter as it will appear in the Property View window
  • unit: this is the default unit used in the Property View window. The options are "cm", "km", "m", "mm", "nm" and "um"
  • default: default value of the parameter. Must be set as "L1_all(2)" to use the value saved in the data file.
  • visible: To make the phase shifter length a user parameter, set to true.  For a fixed length thermal switch, set to false.
  • annotate: enable or disable annotating the parameter value in the element.
  • min, max: minimum and maximum values allowed for the thermal switch length. The user will be warned when trying to set a value outside this range.

ER_V1

Struct

The extinction ratio (dB) of the switch (as explained in the Spectrum Data Visualization in photonic model page) at the power given by ER_P1_power provided as a struct. The struct has the following fields:

  • default_value: The nominal extinction ratio at ER_P1_power in dB.
  • visible_to_user: Boolean flag to turn this FOM into a visible parameter for the CML user.
  • min: If the FOM is used as a parameter then the minimum allowed value in dB.
  • max: If the FOM is used as a parameter then the minimum allowed value in dB.

Fields "min" and "max" are optional and must be provided only when "visible_to_user" is set to 1 (true).

Note: Used for unbalanced switches only.
ER_P1_power

Number

thermal phase shifter power (W) for which ER_V1 is provided.
Note: Used for unbalanced switches only.
