Job description

We aim at laying the foundations for a new generation of laser systems that utilize semiconductor nanocrystals as the gain medium. In particular, the research will focus on colloidal nanocrystals synthesized using wet chemistry, with special attention to perovskite-based materials, to form optically pumped CW microlasers. Lasers will be fabricated using UGent’s proven nanocrystal-in-silicon nitride technology, which readily allows for the integration of multiple lasers on a single chip. This multidisciplinary project involves multiple aspects, including:

1. The synthesis of new nanocrystals for optical gain, covering the visible and near IR wavelengths.

2. The characterization of colloidal nanocrystals as optical gain material using advanced optical spectroscopy.

3. The design, formation and characterization of individual nanocrystal-based microlasers.

4. The integration of nanocrystals-based microlasers in multilaser systems. Intermediate results will be discussed with a user committee of local companies to come to an operational and useful laser demonstrator by the end of the project.

Profile of the candidate

The Ph.D. student will focus on the synthesis and characterization of a new generation of colloidal semiconductor nanocrystals for optical gain applications, aimed at covering the full visible and near infrared spectrum. Gain characteristics will be measured using advanced optical spectroscopy, including femtosecond pump-probe transient absorption and photoluminescence spectroscopy. The work will be executed at the Physics and Chemistry of Nanostructures Group of Ghent University, Belgium. The Ph.D. candidate will be offered a 2-year scholarship, with a possible 2 year extension, and must enroll as a PhD student at Ghent University. T
