Develop the next-generation, low-cost fiber packaging solution for Silicon Photonics.

Senior Silicon Photonics Packaging R&D Engineer

What you will do

Over the past several years, imec has developed a state-of-the-art silicon photonics (SiPho) technology for realizing next-generation optical interconnects as well as novel optical sensing applications. However, in order for SiPho to break into high-volume, low-cost applications, a cost-effective process for single-mode fiber packaging needs to be developed. As a Senior Silicon Photonics Packaging R&D Engineer, you will be the technical lead in the technology pathfinding for next-generation SiPho optical packaging, and you will work with imec’s photonic and 3D integration engineers to demonstrate such desired low-cost packaging solution. In order to achieve this goal, you will design innovative fiber coupling structures (including beam shaping and mechanical support structures), which will be fabricated using wafer-scale silicon processes in imec’s clean room. In addition, high-throughput wafer-scale fabrication or assembly of micro-optical components on the SiPho platform will be pursued. You will carry out this work in collaboration with material suppliers, vendors of optical fiber connectors, advanced semiconductor packaging/assembly tool vendors, as well as OSATs.


  • Conceive novel concepts for low-cost fiber packaging through optical/mechanical design and modeling of SiPho coupling interfaces
  • Design a high-throughput monolithic/hybrid wafer-scale process flow to realize the designed interfaces in imec’s SiPho platform 
  • Design process/layout experiments to drive technology development
  • Test, evaluate and qualify the developed packaging solution (optical/mechanical/reliability)
  • Drive project execution by interacting with integration, test & reliability engineers within imec, as well as with external vendors
  • Document and report to internal and external stakeholders including imec’s partners and customers
  • Report to the scientific community at conferences or in scientific journals
