Specialized Course in

Silicon Photonics Design

Ghent University in collaboration with ePIXfab is offering a specialized course on silicon photonics. This unique course provides an opportunity to the participants to design, fabricate and test their idea by prototyping their own silicon photonics chip. This “all-in-one course” takes the participants through the complete silicon photonics design flow in a step-by-step way.

The course has two parts. In the first part, the participants learn about the silicon photonics design flow. They use this knowledge to conceive a design idea and transform it into a design rule compliant layout, which is afterward fabricated by Australian Silicon Photonics. In the second part, the participants get an opportunity to characterize their design by using the measurement facilities of photonics research group at Ghent University.

Learn to make and test your own silicon photonics chip

The scope of this course covers the silicon design methodology in complete detail. The know-how of the participants is enhanced to a level that they can easily transform their design idea into a working prototype and characterize it.

The course focuses on the fundamental understanding of the many concepts in the PIC design process. While it is not intended as a training for specific design tools, it makes use of interactive Python notebooks using Luceda’s IPKISS framework.

The course is specially designed for early career academic or industrial researchers and engineers who want to learn or enhance their learning about what it takes to make a working prototype in silicon photonics.

Brussels National Airport
Ghent is only 60 minutes from the international airport of Zaventem ‘ Brussels Airport”, where flights arrive from and depart to more than 70 destinations. There are two direct trains per hour between the airport railway station (Brussel-Nationaal-Luchthaven) and the railway station, Ghent-Sint-Pieters (Gent Sint-Pieters station).

In the airport, follow the signs to the railway station. Buy a ticket for Ghent-Sint-Pieters station at the counter in the train station of the airport or online on http://www.belgianrail.be/en/. Booking online avoids long ques at the ticketing counters.

Apart from direct trains to Ghent, you can take the shuttle train to Brussels Central Station from the airport (4 trains in each hour). There, you can change to a train to Ghent-Sint-Pieters.

More information on transport to and from Brussels Airport can be found on http://www.belgianrail.be/en/.

Charleroi Brussels South Airport
There are two options for traveling between Charleroi (Brussels South) Airport and Ghent:
Option 1: Bus + Train
More information can be found at http://www.charleroi-airport.com/en/acces/train-bus/index.html
Option 2: Shuttle bus to Ghent (or Brussels)
More information can be found at http://www.charleroi-airport.com/en/acces/shuttle-buses/index.html 

By High-Speed Train:
The closest international railway station for high-speed trains is Brussels South (Bruxelles Midi) railway station (arrival of Thalys, TGV, Eurostar, ICE, etc.).

Regular connections by train to Ghent-Sint-Pieters railway station are available (approximately 2-3 trains per hour) with a journey time of approximately 30 minutes. Train schedules are available at  www.b-rail.be/main/E/.

By International Bus:
If you’re planning to travel by bus or coach, you can contact Eurolines (http://www.eurolines.be/), which runs coach services to many destinations in Europe. Ghent is one of them. The bus stops at Koningin Elisabethlaan 73, which is near the Ghent Sint-Pieters train station.


The course participants have to arrange their own accommodation. There are plenty of options for a short stay in Ghent. For price and availability, check the following links. If you have any difficulties finding suitable accommodation please send an email at info@ePIXfab.eu.

About Course Instructor

I graduated in engineering (applied physics) at Ghent University in June 1998. He joined the Photonics Research Group of Ghent University-IMEC for a PhD, building the design and technology foundations for IMEC’s first silicon photonics technology platform on 200mm CMOS tools. This led to collaborations with tens of partners, growing into a silicon photonics multi-project-wafer service in IMEC, eventually known as ePIXfab. To enable the design of these photonic chips, I and my colleagues develeoped the software package IPKISS, a parametric design framework for photonic circuits.

In 2010, I became Professor at Ghent University, specializing in advanced design methodologies for integrated photonics, tackling the challenges that form the design gap for silicon photonics. With the growing industrial interest in silicon photonics, this know-how became ever more relevant for a larger community. In June 2014, I co-founded Luceda Photonics, a Ghent University – IMEC- VUB spin-off to bring the IPKISS software and other advanced design tools to the rapidly growing photonics market.

With Luceda Photonics successfully established in the Integrated photonics market, I returned full-time to my fundamental research interest. Since October 2016, I am again full-time at Ghent University and IMEC with a growing research activity in large-scale silicon photonics and programmable photonic circuits. On this topic I received the consolidator grant PhotonicSwarm from the European Research Council (ERC).

I am a very strong adept of Agile and Lean philisophies, with a passion to apply them to the peculiar ecosystem of academic research, as well as my personal life.

I am co-author of over 200 publications in the field of silicon photonics and design methodologies, including many invitations to international conferences. He holds several patents in the field of photonics and its applications. I am a member of IEEE, OSA, SPIE and the Scrum Alliance.


ePIXfab is the European Silicon Photonics Alliance. Its mission is to promote silicon photonics science, technology and applications. ePIXfab represents the European Silicon Photonics at the global scale and enables access to European silicon photonics technology to industry and academia through by training, workshops and road mapping activities.

The photonics research group of Ghent University, headed by Prof. R. Baets, is actively working on the design and fabrication of SOI and SiN-based photonic devices using standard lithographic techniques compatible with CMOS-processing. 100- members of the group are working on the various application of silicon photonics ranging from information and communication technology to sensing and life sciences.

Luceda Photonics wants photonic IC engineers to enjoy the same first-time-right design experience as electronic IC designers. Luceda Photonics’ IPKISS tools and services are rooted in over 50 years of experience in photonic integrated circuit (PIC) design. IPKISS assures that Photonic Integrated Circuit (PIC) designers have full control of their design framework to make sure that what they fabricate matches exactly how they designed it.


The Australian Silicon Photonics team has been designing and fabricating integrated optics devices for more than 15 years. For the last decade, the group has focused on mass-manufacturable silicon photonics device fabrication using the leading-edge electron-beam lithography (EBL) and wafer processing equipment at the Australian National Fabrication Facility’s (ANFF) Melbourne Centre for Nanofabrication (MCN) and RMIT’s MicroNano Research Facility (MNRF).

Australian Silicon Photonics has developed a capability to reliably design, fabricate and characterise Silicon Photonics devices with similar geometries as the imec SiPhotonics passives technology.
