We have an opening for an experimental PhD project in the Quantum and Laser Photonics Group. The project will focus on new types of semiconductor lasers for applications in quantum and information technology. Our group recently made a breakthrough in laser research by demonstrating a nanolaser with the smallest threshold current ever measured. In this project, we want to explore new regimes of laser physics by exploiting the concepts of Fano resonances and extreme confinement of light.  The overall motivation is to realise a new generation of microscopic lasers with ultra-high speed, reduced quantum noise and near-unity quantum efficiency. This requires progress within several scientific disciplines, including the theory and modelling of light-matter interaction in nanostructures, nanofabrication and experimental characterisation of nanophotonic devices. The present project will mainly focus on fabrication and experimental characterization, but will also involve modelling and design.

The project is part of a major leading-edge research activity at the Technical University of Denmark focusing on the physics and application of semiconductor nanophotonic structures and bringing together researchers from several departments at DTU. The research is funded by an ERC Advanced Grant from the European Research Council and a Center of Excellence Grant from the Danish National Research Foundation (see www.nanophoton.dtu.dk).

Responsibilities and tasks
The project is mainly experimental and involves work in DTU’s state-of-the-art cleanrooms and optical labs. The specific tasks include laser simulations, with a specific emphasis on electrical properties, mask design, e-beam lithography and experimental characterization of fundamental laser characteristics. The ambitious goals of the project are addressed as a collaborative effort, involving a team of researchers with expertise in the relevant scientific fields  

As part of the Danish PhD program, the student will follow a number of PhD courses, take part in teaching and conduct and external research stay.

Candidates should have a two-year master’s degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master’s degree. Candidates with a strong background in one or several of the following topics are preferred: photonics, solid-state physics, quantum optics, or nanoelectronics. Experience from working in a cleanroom or optical laboratories an strong advantage. Only candidates with a GPA belonging to the very top or a proven track-record of relevant research can expect to be called for interview.

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 at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see DTU’s rules for the PhD education.

Candidates will be assessed by Professor Jesper Mørk, Senior Researcher Yi Yu, and Professor Kresten Yvind.
