Variable Type Description

temperature_data

 Number  Temperature in units of Kelvin at which the provided spectrum data of the grating coupler was measured or simulated.

peak_IL_dB

 struct

Insertion loss in dB at the peak transmission from port 1 to port 2 of the grating coupler for both TE and TM modes provided as a struct. The struct has the following fields:

  • default_value: 1 x 2 matrix of IL values for both modes
  • 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 meter.
  • max: If the FOM is used as a parameter then the minimum allowed value in meter.

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

Note: The order of TE and TM data in each matrix should be consistent throughout the data file.

R1_dB

 struct

Reflection at port 1 in dB for both TE and TM modes provided as a struct. The struct has the following fields:

  • default_value: 1 x 2 matrix of reflection values for both modes
  • 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 meter.
  • max: If the FOM is used as a parameter then the minimum allowed value in meter.

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

Note: The order of TE and TM data in each matrix or cell should be consistent throughout the data file.

R2_dB

 struct

Reflection at port 2 in dB for both TE and TM modes provided as a struct. The struct has the following fields:

  • default_value: 1 x 2 matrix of reflection values for both modes
  • 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 meter.
  • max: If the FOM is used as a parameter then the minimum allowed value in meter.

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

Note: The order of TE and TM data in each matrix or cell should be consistent throughout the data file.

mode_data

 struct

A cell array containing the mode information. Each struct contains the following fields:

  • name: The name of the mode (TE or TM)
  • ID: The ID that the mode is identified with. This number should be consistence with the order in which TE and TM mode information is stored in matrices. (eg. the insertion loss at peak for the mode with ID=1 is found in peak_IL_dB(1) and for mode with  ID=2 is found in peak_IL_dB(2))

mainpol_ID

 number

The ID of the mode which the grating coupler is designed for and identifies as the main polarization. (1 or 2)

bandwidth_1dB_mainpol

 struct

1dB bandwidth for the main polarization in meters provided as a struct. The struct has the following fields:

  • default_value: A single number for 1dB bandwidth for the main polarization in meters
  • 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 meter.
  • max: If the FOM is used as a parameter then the minimum allowed value in meter.

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

peak_wavelength_mainpol

 struct

The wavelength at the peak transmission for the main polarization in meters provided as a struct. The struct has the following fields:

  • default_value: A single number for the wavelength at the peak transmission for the main polarization in meters
  • 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 meter.
  • max: If the FOM is used as a parameter then the minimum allowed value in meter.

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

skew_mainpol

 struct

The offset of the peak wavelength from the wavelength at the center of the band in meters for the main polarization provided as a struct. The struct has the following fields:

  • default_value: A single number for the offset of the peak
  • 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 meter.
  • max: If the FOM is used as a parameter then the minimum allowed value in meter.

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

dpeakwavelength_dT_mainpol

 struct

The change in peak wavelength with change in temperature in m/K for the main polarization provided as a struct. The struct has the following fields:

  • default_value: A single number for the change in peak wavelength
  • 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 meter.
  • max: If the FOM is used as a parameter then the minimum allowed value in meter.

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