The Photonics and Semiconductor Nanophysics group at the Eindhoven University of Technology (The Netherlands, http://www.tue.nl/psn) has an open PhD student position in the field of quantum light sources in optomechanical cavities.
Goal and background
Quantum emitters coupled to nanoscale optical cavities enable a new generation of nanoscale light sources, including single-photon sources for quantum information processing and nanolasers for on-chip optical communications. Recently, optomechanical nanophotonic cavities have been developed where the properties of the optical modes are changed by nm-scale mechanical displacement of a moving part. In this project we intend to investigate how these optomechanical effects can be exploited to control the photon emission process – at the quantum level - in a cavity. Specifically, we will investigate the spontaneous and stimulated emission of semiconductor nanostructures (quantum dots) in optomechanical photonic crystal cavities. This will lead to the demonstration of novel nanolasers which can be modulated through the mechanical motion and of quantum interfaces between charges, phonons and photons for application in photonic quantum information processing.
The selected candidate will perform fundamental research at the interface between nanophotonics, quantum optics and optomechanics. He/she will conceive solid-state nanophotonic structures based on photonic crystals with embedded semiconductor quantum dots and will use them to experimentally investigate the radiative emission of the quantum dots in the presence of a mechanically-oscillating optical cavity. Specific goals include the mechanical control of spontaneous and stimulated emission rates of quantum dots – crucial for quantum information processing – and the investigation of the novel dynamics expected in nanolasers where the cavity field is coupled to mechanical motion, such that it can be potentially turned into a laser emitting phonons as well as photons. The project will be carried out in close collaboration with the "Photonic forces" group at AMOLF (Amsterdam), and co-supervised by Prof. A. Fiore (TU/e) and Dr. Ewold Verhagen (AMOLF).
We welcome applications from candidates with a Master degree in physics with top marks and with a background and interest in optics or photonics. Candidates must prove a strong attitude towards experimental physics and the drive and capacity to tackle different aspects of a complex problem with large independence.
