Matlab GDS Photonics Toolbox
This is a Matlab library of functions to facilitate the design of Photonics Integrated Circuits GDS layouts that I have developped with Alexandre D. Simard during my PhD.
This is oriented towards intuitive and adaptable creation of GDS layout files for fabrication in different facilities across the world. The toolbox creates a GDS based on a general layer map, but can be set up to export to any other layer map once the design is done.
Nicolas Ayotte and Alexandre D. Simard have used this library to efficiently create multiple layouts for different fabrication facilities across the world with successful results.
- Relative orientation group waveguide routing including turns, tapers, s-bends and the possibility to customize inter-waveguide distance at any point.
- Access to the travelled distance (physical or optical) of any waveguide offering a quick way to measure your devices.
- Possibility of referencing premade structures (fiber couplers, directional couplers, detectors, etc.)
- Possibility of referencing custom structures created on the fly.
- Premade functions for microrings, Bragg gratings, multi-mode interferometer, contra-directional couplers, output array of fiber couplers, etc.
- Tutorial project with many cells showcasing the features.
- A PDF presentation presenting the library's purpose and principles.
- Intuitive relative cell placement in the master floorplan for easy teamwork.
- Relative and scalable routing solution.
- Includes functions to export to other layer maps, including boolean operations on the layers.
- Easy scripting language (i.e.: Matlab).
It is strongly encouraged to get the free software KLayout to look at your GDS files:
Suggested first steps
- Look through the PDF presentation
- (Optional) Run the command "mex -setup" to install a C compiler in matlab.
- Run the makemex.m function in the main folder to compile all the C functions needed for the library.
- Open the tutorial project folder: Project - New Project
- Go through the Cells script, run them, look at the resulting .gds files.
- Look at the Cell_RoutingWG.m script that places the cell in the floorplan.
- Read at the ProjectDefinition.m file.
- Run the Main.m to merge the gds cells and export to the ouput layer map.
- Duplicate the Project folder and make your own!
