Siden vil vise de projekter som blev valgt i foråret 2014. Der vil være et resumé for hvert projekt, som er skrevet i begyndelsen af projektet.
1. Development of MATLAB Software for Measuring Structural Colors
Nicolai Thomassen s123522, Lea Sass Berthou s123901
Vejleder: Emil Højlund-Nielsen, DTU Nanotech
Resumé:
This report describes the development and implementation of MATLAB software for measuring of reflection and transmission. The project is introduced with motivation, goal and a theory section with the physics behind optics. This includes Maxwell’s equations, the derivation of the Fresnel equations and wave theory. This is followed by a study of optical surfaces in general, associated with typical measurement situations. Then the code structure, design and implementation of functions and scripts is presented, especially with user-friendliness taken into consideration. Our focus in the coding are:
-
Low-level functions to control the components
-
Development of a command-line toolbox to interact with the mechanical and optical components
-
Development of a GUI, Graphical User Interface, app with focus on transparency and user-friendliness
The MATLAB software is developed using the Johnson coding-standard. The developed software will be used for angle resolved measurements of a number of different samples and the tests will be compared to prefabricated reference-samples. Finally a conclusion will sum up whether the goals of the project have been met.
2. Modeling few-emitter nanolasers in cavity quantum electro-dynamical systems
Alexander K. Reumert, s123495, Simon M. Nielsen, s123902
Vejledere: Anders Mølbjerg Lund, Anders Nysteen, DTU Fotonik
Resumé:
There is an ongoing effort to understand and utilize quantum dots as a gain material in nano-sized lasers. Fabrication of these dots will lead to an uneven distribution of different sized quantum dots, and therefore emitted light. Thus have an impact on the functionality of the laser. This impact is modelled through laser rate equations, quantum dot distributions and numerical simulations.
3. Optomagnetic measurements on magnetic nanobeads in oscillating magnetic fields
Andreas Ejdrup Lauritzen (s123945), Mathias Kasper Huss-Hansen (s123218), Mathias Kasper Huss-Hansen (s123218)
Vejleder: Mikkel Fougt, DTU Nanotech
Resumé:
The goal of the project is to create and characterize a rotating oscillating magnetic field. This can be used to detect magnetic nanobeads in optomagnetic biosensors. Our experimental setup will consist of 4 coils to create a 2-dimensional adjustable magnetic field. In DTU nanotech there has been conducted experiments on nanoparticles using uniaxial oscillating magnetic fields and we wish to compare that experiment configuration with ours.
