Photonic integrated circuit (PIC) technology powers the modern internet, enabling video calls, data-mining and associated cloud services. Besides that, PIC technology is also penetrating into applications of medical diagnostics, sensing and ranging, quantum signal processing and artificial intelligence. These applications are driving unprecedented levels of integration and complexity. But the circuit-level performance metrics are stretching the limits of the established PIC platforms. The three major PIC platforms, namely InP, silicon and silicon nitride (SiN), each excels in certain key metrics, but also shows critical weakness.
It is the goal of the EU H2020 project INSPIRE to combine the power of InP technology with the full capability of silicon and SiN photonic technology, creating and leveraging volume manufacturing techniques. INSPIRE will leverage micro-transfer printing technology to realize heterogeneous InP/SiN photonic integrated circuits, combining the best of both the InP and Si/SiN photonics technologies. Wafer scale coverage of InP devices on SiN circuits will be enabled, using new and innovative hybrid building blocks and printing methods. This can facilitate order-of-magnitude changes in density, performance and function of the PICs.
Within the INSPIRE project, we have one postdoc researcher open position at TU/e. The main task of the postdoc will focus on novel epitaxial growth and regrowth technologies on the InP coupon, to achieve higher integration density and better thermal management in an array of active devices, e.g., semiconductor optical amplifiers (SOAs), lasers, electro-optic modulators and photodiodes. It is also the ambition to integrate multiple active functions within one coupon, which has not been achieved before. The postdoc will collaborate closely with a PhD student within the same project, looking over the overall technology development at a higher level.
The postdoc will also collaborate with INSPIRE partners in various work packages.
The Institute for Photonic Integration (IPI) has five dynamic and ambitious research groups, which are closely cooperating: a systems group, a photonic integration technology group and three materials research groups. You will work in the Photonic Integration group (PhI) which has about 35 members, 20 of which are PhD students. The IPI (previously COBRA) is internationally leading on advanced InP-based Photonic Integrated Circuits technology.
See http://iopscience.iop.org/article/10.1088/0268-1242/29/8/083001. The technology development and device realization will be supported by experienced technicians in our
world-class cleanroom facilities at Nanolab@TU/e (www.tue.nl/nanolab).
