Luceda PDK for SiEPIC Shuksan
The Luceda PDK for SiEPIC Shuksan allows to design and tape out to the first ever laser integration multi-project wafer (MPW) run offered by SiEPICfab.
Contents
PDK Documentation
This document explains how to use the Luceda Process Design Kit (PDK) for SiEPICfab (version 0.2.3.luceda2).
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.

Grating Coupler Matrix
GratingCouplerMatrix
Fully parametric matrix of grating couplers, including parameters for placing the routing waveguides. Circuit model is derived from the hierarchical model.
- Parameters:
- add_extensions: ( bool, bool_, bool or int )
Adding extensions to the output waveguides for easier and more robust external routing
- gc: PCell
Grating coupler cell (only for 1D gratings)
- gc_sep_x: float and number > 0
Horizontal separation between the grating couplers
- gc_sep_y: float and number > 0
Vertical separation between the grating couplers
- n_cols: int
Number of GC columns
- n_rows: int
Number of GC rows
- wg_radius: float and number > 0
Radius of the routed waveguide bends
- wg_sep: float and number > 0
Separation between the waveguide
- wg_str_len: float and Real, number and number >= 0
Length straight wavelength at the GC port
- exposed_ports: ( dict ), *None allowed*
Ports to be exposed, mapping {‘instance_name:port_name’: external_port_name’} map for i3.expose_ports().Set to None (default) to expose all unconnected ports
- insts: OrderedDict and key: str, value: PCell, _View
Instances of child cells which this circuit is composed of: {‘instance_name’: cell, …} where cell is an i3.PCell object.
- specs: list
Placement and routing specifications
- strict: ( bool, bool_, bool or int )
If True, any error will raise an exception and stop the program flow. If False, any routing error will give a warning and draw a straight line on an error layer. See
i3.ConnectLogicalfor more information.- name: String that contains only ISO/IEC 8859-1 (extended ASCII py3) or pure ASCII (py2) characters

Splitter Trees
ShuksanSplitterTree
Custom splitter tree for the SiEPIC Shuksan PDK, where the vertical spacing of the output waveguides is not constant. The output waveguides are distributed over several waveguide groups in which the waveguides are closer together than the vertical distance between those groups. Circuit model is derived from the hierarchical model.
- Parameters:
- n_wg_groups: int
Number of grouped output waveguides (or sub splitter trees)
- n_wgs_per_wg_group: int
Number of waveguides per group
- spacing_y_groups: float and number > 0
Vertical spacing between the groups
- spacing_y_ports: float and number > 0
Vertical spacing between the output ports
- splitter: PCell
Splitter used
- wg_radius: float and number > 0
Radius of the routed waveguide bends
- exposed_ports: ( dict ), *None allowed*
Ports to be exposed, mapping {‘instance_name:port_name’: external_port_name’} map for i3.expose_ports().Set to None (default) to expose all unconnected ports
- insts: OrderedDict and key: str, value: PCell, _View
Instances of child cells which this circuit is composed of: {‘instance_name’: cell, …} where cell is an i3.PCell object.
- specs: list
Placement and routing specifications
- strict: ( bool, bool_, bool or int )
If True, any error will raise an exception and stop the program flow. If False, any routing error will give a warning and draw a straight line on an error layer. See
i3.ConnectLogicalfor more information.- name: String that contains only ISO/IEC 8859-1 (extended ASCII py3) or pure ASCII (py2) characters
The unique name of the pcell
- Other Parameters:
- n_levels_groups: int, locked
Number of group levels
- n_levels_ports: int, locked
Number of port levels within a group
- spacing_x: float and number > 0, locked
Horizontal spacing between the levels

Waveguide Bragg Gratings
WaveguideBraggGrating
Parametric Waveguide Bragg Grating (WBG). In this WBG, you can include chirp, apodization, an offset between the gratings on both sides of the waveguide, and you can choose between a rectangular or sinusoidal grating. The gratings have a standard duty cycle of 50%, but this can be adapted (only for the rectangular grating).
- Parameters:
- apodized: ( bool, bool_, bool or int )
Cosine apodization
- corrugation_width: float
Corrugation width [um]
- grating_chirp: float
Linear chirp parameter of the grating, meaning the difference in grating period at start and end [um]
- grating_duty_cycle: float and number > 0 and ]0.0,1.0[
Factor for the wide section (width of the wide section divided by grating period)
- grating_offset: float and Real, number and number >= 0
Horizontal offset between top and bottom grating
- grating_period: float and number > 0
Grating period at the center unit cell(s) [um]

Rectangular (‘RECT’) or sine (‘SINE’) grating
- n_periods: int and number >= 0
Number of periods
- width: float and number > 0
Average width of the grating [um]
