A 3-year PhD position is available in the Structured Electromagnetic Materials group at DTU Fotonik, Department of Photonic Engineering at the Technical University of Denmark. The PhD project is funded by the Danish National Research Foundation, and will be carried out in close collaboration with DTU’s Centre of Excellence in Nanostructured Graphene (CNG) and with Prof. Fengnian Xia’s group at Yale University, where the student will spend a few months as an external stay during the PhD study.

Silicon based optical interconnects offer a promising solution to solve the communication bottleneck faced by the electric interconnects, and intensive efforts have been devoted to developing compact integrated photonic elements including laser source and photodetector. However, due to indirect bandgap of silicon, these devices are often realized by integrating other gain materials, e.g., germanium or III-V compound semiconductor, thus leaving us a big challenge for reducing the fabrication cost and direct monolithic integration with CMOS technology. Two dimensional (2D) layered materials, such as graphene and transition-metal dichalcogenides (TMDC), have shown great potential to realize components that can easily be integrated with Si devices. The purpose of this project is to explore and develop a novel class of 
lasers and photodetectors relying on two-dimensional materials integrated with silicon photonic chip, which is CMOS-compatible, and suitable for chip-level integration. The project comprises explorations on two-dimensional material physics, design and fabrication of photonic chips, and characterization of the device performances, and it will be carried out in close collaboration with Yale University.

Candidates should have a master's degree in Engineering/Physics or a similar degree with an academic level equivalent to the master's degree in Engineering/Physics. Priority will be given to students with experience in experimental nano-optics, silicon photonics and clean-room experience.

Approval and Enrolment
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes of DTU. For information about the general requirements for enrolment and the general planning of the scholarship studies, please see the DTU PhD Guide.

The assessment of the applicants will be made by Assoc. Prof. Sanshui Xiao, Assoc. Prof. Nicolas Stenger, and Assoc. Prof. Martijn Wubs.
