Composite Waveguides (Virtuoso Photonics Option)

You will need the Virtuoso_Photonics_Option license to use the functionality discussed in this section. For information on obtaining the required license, contact your local Cadence representative.

If you are using the Virtuoso Photonics Solution and have the Virtuoso_Photonics_Option license checked out, Layout XL enables you to use optical connections called waveguides in your design. When several such optical connections or waveguides are used in a design, the resultant waveguide is called a composite waveguide.

The Virtuoso Photonics Solution supports the generation of such composite waveguides using the Generate All From Source command, and supports editing of the composite waveguides using the Composite Waveguide Editor. Each component of the composite waveguide is called an Element.

The Composite Waveguide Editor can be launched from both the editors, schematic and layout. If launched in the Schematic view, the Composite Waveguide Editor allows early estimation of the waveguide geometry.

The various ways you can launch the Composite Waveguide Editor in the schematic and layout view are:

• From the Create Instance form
  When creating a composite waveguide instance, click the Ellipses (…) button corresponding to the Edit label displayed just above the Waveguide parameter list.
• From the Property Editor assistant
  In the Property Editor assistant, click the Ellipses (…) button corresponding to the Edit label displayed just above the Waveguide parameter list.
• From the Property Editor form
  In the Parameters tab of the Property Editor form, click the Ellipses (…) button corresponding to the Edit label displayed just above the Waveguide parameter list.

Editing a waveguide can involve the following:

• Adding a Waveguide Element
• Deleting a Waveguide Element
• Changing the Position of a Waveguide Element
• Adding an Optical Connector
• Waveguide Element Rotation
