PhD - Leuven | More than two weeks ago
Optical instrumentation has a key role in life science research and diagnostics. Optical techniques based on fluorescence, absorption, spectroscopy, microscopy etc are routinely used in the clinical practice. For reasons of performance, cost and form factor, free space optics is recently increasingly replaced by integrated photonics, which allows to integrate a wide variety of optical functionality on a small chip, lowering cost and increasing functionality per area. Especially in fields such as DNA sequencing this has led to new breakthroughs in the application space. While both passive and active nanophotonic circuits can now be fabricated in several pilot lines, the integration of light sources and detectors is lagging behind. Indeed, packaging of the chips to interface with sources and detectors currently is the bottleneck and limiting a wider uptake in the field.
Imec is working on integrating visible lasers and detectors on top of its silicon nitride waveguide platform. In this PhD you will take advantage of these integrated sources and detectors and build photonic integrated circuits for specific applications in the life sciences field, such as fluorescent biosensors and cellular cytometry. The circuits will need to take into account the application requirements, the interfacing with the integrated sources/detectors and the possible parasitics induced by them. The work comprises both system and device modeling and experimental validation of the device concepts.
