Luceda PDK for SiEPIC
The Luceda PDK for SiEPIC allows to design and tape out to SiEPICfab, the Canadian SiEPIC silicon photonics foundry.
Several training courses are organized on the basis of this PDK. In the edX Silicon Photonics Design, Fabrication and Data Analysis course, which runs for 6 weeks, you can design photonic circuits using this PDK, submit your design for fabrication and have it tested.

PDK Documentation
This document explains how to use the Luceda Process Design Kit (PDK) for SiEPICfab (version 0.3.36.luceda3).
The PDK can be used from Luceda IPKISS, providing the following functionality:
definition and layout of circuits using SiEPIC’s predefined library of cells (building blocks), which is entirely available within IPKISS,
waveguide routing using the waveguide types defined, or custom defined waveguides following design rules,
definition of custom devices using defined layers and design rules,
simulation of custom devices using IPKISS’ built-in solvers and IPKISS Links to 3rd party tools such as Dassault Systemes Simulia CST Studio Suite ® and Ansys Lumerical FDTD,
circuit editing from Siemens L-Edit using Luceda Link for Siemens EDA.
This documentation explains how to get started with the PDK, lists the cells that are available and documents the technology for custom design.

EbeamAddDropAsymmStraight
Asymmetric add-drop ring (racetrack) resonator, meaning the gap between the ring and bottom adjacent waveguide is different as the gap between the ring and top adjacent waveguide.
- Parameters:
- gap1: float and number > 0
Gap between the ring waveguide and the straight waveguide at the input [um]
- gap2: float and number > 0
Gap between the ring waveguide and the straight waveguide at the output [um]
- coupler_length: float and Real, number and number >= 0
Length of the coupling section [um]
- ebeam_res: String that contains only alphanumeric characters from the ASCII set or contains _$. ASCII set is extended on PY3. and List with value restriction, allowed values: [‘6NM’, ‘1NM’, ‘2NM’]
Resolution of the EBeam, 6NM = normal 6 nm shot pitch, 2NM = 2 nm shot pitch
- offset_length: float
Length of the waveguide section at the ports [um]
- orthogonal_identifier: int
Indicating whether we excite the component (1: TE, 2: TM)
- radius: float and number > 0
Radius of the ring [um]
- wg_width: float and number > 0 and [0.4,3.5]
Width of the core [um]
