Port Definitions

Variable Type Description
ports Cell

A cell array containing structs which have information about each port. Every struct must contain the following fields:

  • name: The name of the port, which will be visible to the end user. This name should be consistent with the name that will be used for netlisting.
  • dir: The directionality of the port, either "Input", "Output", or "Bidirectional"
  • type: The signal type of the port, which should be "Optical Signal" for waveguides
  • pos: The side of the model which the port will be displayed on, either "Left", "Right", "Top", or "Bottom"
  • loc: The placement of the port on the side defined by loc, provided as a coordinate between 0 and 1.
opt_1_RELAY number

The indices of the cells in the 'ports' cell array, that corresponds to the first and second optical ports (on the first bus).
opt_2_RELAY number

Photonic Model 

Variable Type Description

photonic_model 

string 

String containing the name of the photonic model used for this template. 

Please visit here for a list of all available photonic models.  

Cosmetic Variables

Variable Type Description
description String A string containing a brief description of the model, which will be displayed to the end user.
prefix String A string containing the prefix of the model, which will be used within interconnect to provide incrementing element names for each successive element that is added to the simulation layout.
notes Cell

A cell array which provides model notes that will be displayed to the end user. Each element of the cell is a struct with the fields:

  • property: The name of the note.
  • value: The contents of the note.

Modeling Variables

Variable Type Description
fir_taps Number

Number of taps for the FIR filter. Larger number allows to resolve frequency dependence better but increases time delay.

Suggestions:

  • Set to ~64 for devices where dispersive properties are important.
  • Set to ~1 for devices that will be used in circuits where time delays are a concern
