Cell

M x 1 cell array, where M is the number of modes. Each element of the cell is a struct with fields:

• name: string with the name of the mode ('TE' or 'TM')
• ID: integer to identify the mode, which should be 1 for 'TE' and 2 for 'TM'. These should be consistent across the entire CML.

Notes:

• This model only supports up to two modes.

Number

Center wavelength (m) of the band for which the waveguide properties below are evaluated.

Temperature (K) for which the waveguide properties below are evaluated.

Matrix

M x 5 matrix containing the effective index of the different waveguide segments, where M is the number of modes and the columns contain the effective index for the:

1. passive waveguide
2. passive to active waveguide transition
3. active waveguide region (at 0V bias)
4. active to passive waveguide transition
5. passive waveguide

Notes: 

• Effective index in transitions can be approximated as the average of the effective index at each side.
• See the Internal Model Diagram in photonic model page for a diagram showing the role of each section.

M x 5 matrix containing the group index of the different waveguide segments, where M is the number of modes and the columns contain the group index of the:

1. passive waveguide
2. passive to active waveguide transition
3. active waveguide region (at 0V bias)
4. active to passive waveguide transition
5. passive waveguide

Notes: 

• Group index in transitions can be approximated as the average of the group index at each side.
• See the Internal Model Diagram in photonic model page for a diagram showing the role of each section.

M x 5 matrix containing the loss (dB/m) of the different waveguide segments, where M is the number of modes and the columns contain the loss of the:

1. passive waveguide
2. passive to active waveguide transition
3. active waveguide region (at 0V bias)
4. active to passive waveguide transition
5. passive waveguide

Notes: 

• Loss for transitions is net loss divided by transition length.
• Loss should be provided as a positive number.
• See the Internal Model Diagram in photonic model page for a diagram showing the role of each section.

M x 5 matrix containing the effective index temperature sensitivity (1/K) of the different waveguide segments, where M is the number of modes and the columns contain the temperature sensitivity of the:

1. passive waveguide
2. passive to active waveguide transition
3. active waveguide region (at 0V bias)
4. active to passive waveguide transition
5. passive waveguide

Notes:

• Background thermal effects can be neglected by setting the values of this matrix to 0.
• See the Internal Model Diagram in photonic model page for a diagram showing the role of each section.

1 x 5 matrix containing the length (m) of the different waveguide segments, where the columns contain the lengths of the:

1. passive waveguide
2. passive to active waveguide transition
3. active waveguide region (at 0V bias)
4. active to passive waveguide transition
5. passive waveguide

Notes:

• The length of the active region (column 3) may be visible to the user, and, if so, contains only the default value for the active region length.
• See the Internal Model Diagram in photonic model page for a diagram showing the role of each section.
