Organisation profile
Photonics is a rapidly growing field where the total market volume is comparable to the market of electronics, and growing even faster. Whereas integrated circuits are already dominant technologies in the field of electronics, photonic integration is still taking off. It is a critical enabler for the modern internet and is poised to enable new forms of sensing and imaging. The Photonics Integration (PhI) group performs leading edge research into indium phosphide semiconductor based technology for photonic integration and its applications. This develops along three research lines listed below ('read more') and involves a number of national and international research projects. Our group offers opportunities for Master and PhD students to do leading-edge research on advanced photonic ICs and technology, and to prepare for a job in a variety of high-tech companies that use photonics, semiconductor technologies, and/or photonic integrated circuits in their products. You might even think to start your own business in this rapidly growing field.
The Photonics Integration research develops along three research lines:
-
Monolithic integration of indium phosphide photonic devices. We have pioneered the generic integration methodology for InP integrated photonics. This approach enables new building blocks to be continuously added to a highly advanced integration platform with seamless integration of lasers with amplifiers, filters, modulators, detectors and more.
-
Heterogeneous and hybrid integration platforms combining indium phosphide circuits with silicon technology, high-speed electronics and low-loss dielectric waveguide technologies. These platforms enable research into new methods of scaling and assembly.
-
Nanophotonic integration using the indium phosphide membrane on a silicon platform. This enables the miniaturisation of photonic devices, and the seamless combination of high confinement photonics, sub-wavelength engineering, lasers and amplifiers.
The technology platforms developed by PhI researchers become available on an open access basis via JePPIX.eu
