Together, we shape the Si-Photonics technology that will define the society of tomorrow.

Germanium-based Si-Photonics Optical Device Engineer 

lmec is a global pioneer in developing integrated silicon photonics technology through its Optical I/O R&D program targeting short-reach optical communications. This technology is successfully offered via wafer-level prototype fabrication services to customers in telecom, datacom, computing, bio-medical, and sensing applications. By leveraging the mature Complementary Metal Oxide Semiconductor (CMOS) processes used in electronics, high-volume and high-yield Photonic Integrated Circuits (PICs) can be fabricated at a relatively low cost. Among the major building blocks in a PIC, the photodetector is critical in interfacing with electronics used for data processing. Besides, standard photodetectors based on p-i-n diodes, imec has been working on the development of Ge-on-Si (A)PDs and monolithic III – V photodetectors. The development aims to target highly sensitive optical receivers for the application of telecommunication and data centers. In this context, the goal is to research optical receivers with optical amplification to achieve low power consumption combined with high sensitivity PDs in the 200 mm and 300 mm platforms at imec.  

What you will do

As a Germanium-based optical device designer, you contribute to further developing germanium photodetectors in our silicon photonics technology as an owner. You act as the technical interface between cross-collaborating teams of Layout design, Epitaxy, process integration, SiPho test, and customers and use their feedback to improve your class of devices. You participate in internal SiPho development runs on 200mm and 300mm to implement improved component designs and you leverage imec’s automated SiPho test stations to implement and test your new device concepts with fast turnaround times. You will be working with a highly talented pathfinding team of 15 under 3DSiP unit who have expertise in their fields and are always curious. 

  • Design state-of-the-art GePD, Ge-on-Si (A)PDs, and GeSi-EAM/PD building blocks in imec silicon photonics platforms, both for 200mm and for 300mm. 
  • Own design test structures, and implement, and document design methodologies for robust Ge-based optical devices (eg. GeSi – EAM/ PDs, etc.). 
  • Simulate, model, design, layout, and characterize (test procedure, data analysis, and reporting) your devices with the tools used in the team and contribute to improved functionality of those Python-based tools. 
  • Build compact models to be used by circuit designers (internal and external customers). 
  • Share your expertise with your colleagues in the silicon photonics group.
  • Interact directly internally and externally. 

Please note that the position is based in Leuven (Belgium). Onsite presence of at least 3 days is required.  

What we do for you

We offer you the opportunity to join one of the world’s premier research centers in nanotechnology at its headquarters in Leuven, Belgium. With your talent, passion and expertise, you’ll become part of a team that makes the impossible possible. Together, we shape the technology that will determine the society of tomorrow.

We are committed to being an inclusive employer and proud of our open, multicultural, and informal working environment with ample possibilities to take initiative and show responsibility. We commit to supporting and guiding you in this process; not only with words but also with tangible actions. Through imec.academy, 'our corporate university', we actively invest in your development to further your technical and personal growth. 

We are aware that your valuable contribution makes imec a top player in its field. Your energy and commitment are therefore appreciated by means of a market appropriate salary with many fringe benefits. 

Who you are

  • You have an excellent understanding of the physics of integrated photonics Ge devices and knowledge of semiconductor manufacturing processes and constraints. 
  • You are curious and creative. You like to collaborate with colleagues using code. 
  • You have demonstrated experience with designing and characterizing high-speed >30GHz electro-optical devices. Simulation (e.g., Ansys, TCAD, HFSS, Agilent ADS) and characterization (S-parameters, TDR, eye diagram & BER measurements) is a plus.  
  • You have experience and are comfortable programming in Python, and with git. 
  • You have run large simulations to explore design spaces and evaluate device sensitivity. 
  • You master your simulation tools (Lumerical and/or RSoft) and understand the pro and cons of each simulation method. 
  • You layout your designs using a scripting language (like ipkiss from Luceda Photonics). 
  • You have good communication skills in English to communicate with your colleagues in our multinational team and with customers. 
  • You have a PhD degree in Physics or Photonics and 3 years of experience in the relevant field will be desirable. 
  • You live in Belgium or are willing to relocate.
