In the past few years, new concepts for general-purpose, programmable photonic integrated circuits (PIC) have been proposed. PICs manipulate light on a chip, often fabricated in silicon or other semiconductors. Today, most PICs are developed for one function, and are therefore called application-specific photonic integrated circuits (ASPIC). The new programmable PICs are more like electronic microcontrollers and field-programmable gate arrays (FPGA), which can be programmed in software for different tasks. Simple programmable PICs have already been experimentally demonstrated, reproducing functionality in programming hitherto limited to custom-designed hardware. This programming is done through electro-optic tuners like waveguide heaters or MEMS. We will discuss different architectures for programmable PICs, and the results of two projects running at Ghent University-IMEC: PhotonicSWARM and MORPHIC, which look. PhotonicSWARM looks into the scaling of programmable PICs with distributed optical paths and control algorithms for the thousands of electro-optic tuners. The MORPHIC project, a collaboration between 6 groups in Europe looks to extend silicon photonics with MEMS to enable programmable circuits which consume little or no power to maintain their programmed state.


Bio Sketch

Wim Bogaerts is professor in the Photonics Research Group of Ghent University and IMEC. He specializes in silicon photonics, design of complex photonics circuits, and programmable photonics. During and after his PhD, he laid the foundations for IMEC's silicon photonics platform, the multi-project-wafer service ePIXfab, and the design software IPKISS, now commercialized by the spin-off company Luceda Photonics. Since 2016, Wim has an ERC consolidator grant, focused on programmable photonics. He is a member of IEEE, the Optical Society, and is a travelling lecturer of the OSA. In 2019 he was also an invited professor at EPFL in Lausanne, Switzerland.
