Offer Description

Create, maintain, and improve the optical interface library devices regarding performance, compact model, and yield.

Imec 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. These activities are growing and require the expansion of our team.  

As an optical interface designer, you contribute to the further development of our silicon photonics platforms. You create, maintain, and improve the optical interface library devices regarding performance, compact model, and yield. This library includes fiber-edge couplers, fiber grating couplers (front and back-side), chip-to-chip edge coupling (e.g. hybrid laser), chip-to-chip coupling on-wafer (a.k.a. wafer stitching) and chip-to-chip adiabatic vertical coupling (e.g. 3D stacking). We work towards state-of-the-art performance: low-loss, loss-reflection, low polarization dependency and high yield. 
Your devices are shared through PDK’s to users of our platforms all around the world. Your devices are certified by external packaging companies. You act as a technical interface with customers and packaging partners 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.   

What you will do
  • Define, implement, and document design methodologies for robust optical interface devices. 
  • Design state-of-the-art optical interface building blocks for imec silicon photonics platforms (SOI and SiN), 200mm and 300mm.
  • Design and maintain test structures for process control and process improvement. 
  • Simulate, model, design, layout and characterize your devices with the tools used in the team and contribute to an improved functionality of those python-based tools. 
  • Own the optical interface devices characterization in the test infrastructure (test procedure, data analysis and reporting). 
  • 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 with customers and packaging partners. 
  • Publish successful results to conferences (OFC and ECOC) and journals.

Education Level
PhD or equivalent

Who you are
  • You have a PhD degree. 
  • You have an excellent understanding of the physics of integrated photonics passive and optical interface devices and knowledge of semiconductor manufacturing process and constraints. 
  • You are curious and creative. You like to collaborate with colleagues using code. 
  • You have demonstrated experience with designing robust optical interface devices (tapers, edge couplers or grating couplers) in Si, SiN, preferably in an industrial context.
  • You have a profound fiber handling and characterization experience.  
  • 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 or gdsfactory). 
  • You have good communication skills in English to communicate with your colleagues in our multinational team and with customers.
