Germanium optical device designer

Updated: about 1 month ago
Job Type: FullTime
Deadline: 10 Oct 2021

As our Germanium Optical Device Designer, you contribute to the further development of germanium photodetectors (GePD) and germanium-silicon electro-absorption modulators (GeSi EAM) in our silicon photonics platforms.

What you will do

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 a germanium optical device designer, you contribute to the further development of germanium photodetectors (GePD) and germanium-silicon electro-absorption modulators (GeSi EAM) in our silicon photonics platforms. You create, maintain and improve the Ge-based library devices regarding performance, compact model and yield. Your devices are shared through PDK’s to users of our platforms all around the world. You act as the technical interface with 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.

Your responsibilities:

  • Define, implement, and document design methodologies for robust Ge-based optical devices.
  • Design state-of-the-art GePD and GeSi-EAM/PD building blocks in imec silicon photonics platforms, both for 200mm as for 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 Ge-based device characterization using imec’s wafer-scale SiPho 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.
