The use of printable nanomaterials, so-called 'quantum dots', as a new class of semiconductors has enable large leaps forward in opto-electronics. Due to their unique combination of low production cost, ease of processing in industrially relevant platforms and unique optical properties, they find applications in mass markets such as displays and lighting. The need for a similar revolution imposes itself in growth sectors where more ...
Elise Verstraelen her PhD thesis reports on a laser spectroscopy study in the actinide region and covers three main topics. Firstly, the results on in-source resonance-ionization spectroscopy of the neutron-rich actinium isotopes 225-229Ac are detailed. These measurements were performed at the TRIUMF ISAC facility in Vancouver and resulted in new data on the changes in mean-square charge radii and the magnetic dipole moments of ...
The low-lying isomer in the Th-229 isotope has eluded physicists for the past decades and received a boost when its existence was proven in 2016. Its low excitation energy around 8 eV presents the only candidate in the entire known nuclear landscape where transportation of laser spectroscopy techniques from the atomic domain to the nuclear one becomes possible. In case this is successful, it opens the door for the development of the ...
The proposed network will establish and support cross-sectorial training and research programme bringing together leading European academic and industrial centers working in the area of optical frequency combs in microresonators (microcombs). The programme will allow to combine and share some of the world leading experience and expertise
in the microcombs and train a new generation of scientists in this actively developing area bordering ...
Over the past decade, optical frequency combs have been used for a growing number of applications, such as chemical sensing, distance ranging, timekeeping, searching for exoplanets, and optical communication. Frequency comb sources in the visible to mid-infrared wavelength range are commercially available, but they are large and expensive instruments. To enable their widespread use, a fully integrated solution is highly desirable.

NOLIMITS will be a Core Facility for non-linear optical microscopy and spectroscopy, supported by
both the Faculty of Sciences and Faculty of Engineering and Architecture. It will serve the UGent research
community and (non-)academic external partners, by grouping over a decade of expertise and advanced
infrastructure related to ultrashort pulsed lasers and the advanced accompanying optical spectroscopy and
microscopy ...
The aim of this project is to develop a new type of heterogeneously integrated microlaser that is sufficiently small and consumes only little power such that it can be combined in large numbers on a single photonic chip. Each laser should have a well-specified wavelength to use the laser array as a spectroscope.
