A single quantum emitter in an optical micro cavity

The goal of this project is to investigate whether two-dimensional van der Waals materials can be used to store quantum information. As a first step we will study the optical emission from these materials; van der Waals materials have already shown fluorescence in the visible regime due to defects in the material. As a second step we will place this material in an optical micro cavity.

In this project, you will use a confocal microscope to scan the van der Waals material for defects and try to quantify the quality of the emitters. To realize this you will:

  1. make a thin film of the materials
  2. build a confocal microscope to find individual emitters and
  3. relate those emitters to the material properties (like strain in sample).

The detection efficiency and interaction strength can be enhanced with an optical cavity.

  • The project runs from 1 September 2021 - 1 September 2022.
  • The project is available in the Fall and Spring semester.
  • Number of placements available: 1 per semester.
  • Also available for undergraduate students who recently graduated.

Prerequisites

  • Student has almost completed a BSc in Physics or is busy with a MSc Physics.
  • Student has sufficient background in optics and quantum mechanics.

Faculty of Science / Leiden Institute of Physics (LION)

The Faculty of Science is a world-class faculty where staff and students work together in a dynamic international environment. It is a faculty where personal and academic development are top priorities. Our people are driven by curiosity to expand fundamental knowledge and to look beyond the borders of their own discipline; their aim is to benefit science and to make a contribution to addressing the major societal challenges of the future.

The research carried out at the Faculty of Science is very diverse, ranging from mathematics, information science, astronomy, physics, chemistry and bio-pharmaceutical sciences to biology and environmental sciences. The research activities are organized in eight institutes. These institutes offer eight bachelor’s and fifteen master’s programs.
