"On-chip alignment of flexible optical waveguides" – Presented by Marcel Tichem, Delft University of Technology

The technology for the fabrication of Photonic Integrated Circuits (PICs) has advanced considerably over the past decades. New generations of photonic packages integrate multi-port PICs from different material platforms to provide more functionality and performance. The assembly and packaging of these devices has become the major cost driver in manufacturing.

The most critical step in photonic packaging is the precision alignment (±0.1μm) of the components and waveguides. We propose a concept and designs where MicroElectroMechanical System (MEMS) functionality is integrated with one of the chips in the package to take care of the fine-alignment of flexible waveguide beams.

Matthijs Langelaar, TU Delft, Presents: "Robust design optimization for integrated photonic systems"

In the field of integrated photonics, uncertainties in fabricated device geometries as well as environmental parameters can dramatically affect performance and yield. To overcome this challenge, this project has developed approaches that allow simulation-based optimization of designs under uncertainties, resulting in robust designs. We have placed emphasis on combining this concept with metamodeling techniques and adaptive infill sampling strategies, to reduce the total computational effort and allow practical application. In this brief presentation, the general approach is introduced together with an overview of the outcomes of the project.
