## Model Development

INTERCONNECT
This element is a compound element that contains the primitive CW Laser element. Several properties are added to the compound to allow users to control the laser, as listed in the table below.

 Name Kind Type Value (default) Unit Category frequency Frequency Number 193.1 THz Laser power Power Number 1 mW Laser linewidth Frequency Number 0 MHz Laser

These property values are inherited by the underlying CW Laser element through the setup scripts of the compound element.

## Test

Download the simulation file ld_cw_basic.icp from the top of this page. In this simulation file, the laser is connected to and measured by an Optical Spectrum Analyzer (OSA). The laser linewidth is set to be 1 MHz in the example file. Click on the “run” button and the OSA will be populated with measurement data. To view the simulation results, right click on the results and select “Visualize”.
