Luceda ADK for PHIX
The Assembly Design Kit (ADK) for PHIX is a design kit for packaging photonic ICs with the PHIX packaging foundry
Contents
PDK Documentation
This document explains how to use the Luceda Assembly Design Kit (ADK) for the PHIX Characterization Package (version 1.1).
The ADK can be used from IPKISS, providing the following functionality:
definition and layout of circuits within PHIX’s Characterization Package, which is entirely available within IPKISS
This document explains how to get started with the ADK, lists the cells that are available and documents the technology for custom design.

License
The use of this ADK is subject to the “PHIX User Non-Disclosure Agreement”.
Usage and responsibility
The use of this ADK is restricted to the design of photonic integrated circuits in the PHIX platform, fabricated by PHIX (Foundry).
All relevant documentation about the PHIX platform, including process description and design rules, can be found in the PHIX Design Manual as provided by the Foundry. The user is advised to carefully read the PHIX Design Manual.
It is the user’s responsibility to verify that the design, made on the basis of this Assembly Design Kit, meets the Foundry’s design rules.
In case of doubt, the user should consider the Foundry’s design rule manual as the correct reference (as validated by the Foundry).
Under no circumstances does LUCEDA represent or warrant that operation of the photonic integrated circuits by the Foundry, designed on the basis of this Assembly Design Kit, will be error-free or will accord to the user specifications, and hereby disclaims all liability on account thereof.

Getting Started
This section explains how to load the Luceda ADK for the PHIX Characterization Package and basics of how to use it.
If you are unfamiliar with IPKISS, please have a look at the IPKISS documentation and samples. The documentation and samples are available from the IPKISS Control Center.
The latest IPKISS documentation is also available online at http://docs.lucedaphotonics.com.
Extracting the ADK
The ADK is distributed as a zip file, which you can extract with the unzip utility of your choice (unzip, WinZip, 7-zip, …).
For the purpose of this manual, we assume you have unzipped “phix.x.x_buildnr.zip” as C:\designs\pdks\phix.
You can inspect the directory structure of the ADK:
docs/: Contains this file
docs/examples/: Example IPKISS python scripts
ipkiss/: IPKISS technology, cells and functions (Python)
techfiles/: Tech files (layers, display) for various tools
techfiles/klayout/: Layer settings for KLayout GDSII visualization
Using the ADK with IPKISS
Setting up the editor environment
You can follow the instructions given in our documentation https://academy.lucedaphotonics.com/tutorials/environment_setup/create_project_pdk.html.
Examples
The ADK comes bundled with a series of examples for use in IPKISS, in the <path_to_pdk>\docs\examples. These are executable Python files. The examples are a good starting point to learn how to design with this ADK. Below is a summary of the shipped examples:
Example name |
Description |
|---|---|
example_ec.py |
Visualize a packaging template using Edge couplers |
example_gc.py |
Visualize a packaging template using Grating couplers |
Technology settings
The ADK contains layer definitions. Note that a IPKISS technology (Luceda PDK) must be loaded before importing the ADK. si_fab will be imported if no other PDK is imported before raising a warning.
Layers
The following table gives an overview of the available layers and how they are named in Ipkiss. See the PHIX design rules manual for further information about the layers defined by PHIX.

ADK Packaging Template
The library contains a number of markers and a packaging template class.
CharacterizationPackage
- class phix.all.CharacterizationPackage(*args, **kwargs)
PHIX Characterization Package Template.
Ports are named according to their side north, south, east and west and numbered from west to east and south to north starting from 1.
For example, “east_1” is most southeast coupler marker if no coupler provided. Otherwise, “east_in_1” is most southeast coupler waveguide port and “east_out_1” is fiber coupling port. “north_1” is the most northwest pad marker if no pad provided. Otherwise, “north_{pad_port}_1” is the {pad_port} of the most west north pad.
