The Electromagnetic Systems (EMS) group at DTU Electrical Engineering invites applications for a 3-year PhD position that focuses on the development and synthesis of photonic circuits.
Quantum Dots (QDs) are a special kind of single-photon sources and belong to the class of deterministic sources. Although the concept of a single photon was already proposed in 1900 by Planck, a true single-photon source was not created in isolation until 1974, and in 1977, evidence of single-photon emission from sodium atoms was observed for the first time.
Single-photon sources are indispensable for photonic quantum circuits and a major driver of the current research into single-photon sources and detectors is the explosive growth of the field of quantum-information science over the last few decades, especially quantum cryptography.

Today's communication infrastructure is facing serious scalability and energy consumption issues, and it will be unsustainable in a not too distant future, if there are no changes in energy consumption trends. The adoption of nano-photonic devices and particularly nano-laser structures can potentially enable dramatic changes to fundamental working principles and power budgets of optical data transmitters.
The research center NATEC (NAnophotonics for TErabit Communications) is exploring novel nano-photonic devices for optical communication. In particular, a novel laser structure based on the Fano resonance in a nano-cavity is showing extremely attractive properties in terms of modulation speed and power efficiency.
The topic of this PhD project is to investigate the applications of the Fano laser and other nano-photonic structures to optical communication systems.

As part of a recently granted Center of Excellence, "Center for Macroscopic Quantum States," a PhD position on experimental quantum optomechanics is offered at the Department of Physics, Technical University of Denmark (DTU). One of the objectives of the center is to control mechanical oscillators using non-classical light and eventually drive the oscillator itself into exotic quantum states .
The PhD project aims to develop and demonstrate novel optomechanical systems tailored for exploring the interface between quantum optomechanics and non-classical states of light. This includes numerical modelling and simulations, cleanroom fabrication, and optical characterization.
All parts of the project will be carried out in close collaboration with other members of the optomechanics team as well as experts on mechanical micro-structuring from other departments at DTU.

The Center for Electron Nanoscopy and the National Center for Nano- and Microfabrication at the Technical University of Denmark (DTU Cen/Danchip) are seeking a PhD student to study, optimize and master the annealing process and to reproduce ‘the old’ but also create novel NEMS devices.
For the successful candidate the quest will be to develop a fundamental understanding of the special challenges involved in surface smoothening at the nanoscale including the physics and chemistry involved. The aim is to establish a generic knowledge platform for nanoscale smoothening for future applications.
The major part of this project will be related to experimental work in the cleanroom facility at DTU Danchip and to demonstrate the ability in some state-of-the-art and novel NEMS applications.
