Schematic illustrating the setup you will be working with.

The Optofluidics group at DTU Nanotech works in the fields of nanofluidics, nano-optics and nanofabrication. In this context, we are investigating optically active waveguiding surfaces with a nanostructure. We call them distributed feedback dye lasers – the nanostructured surface actually emits laser light! These surfaces can be used as sensors for biological applications. The read out of the sensor’s signal works by focusing a laser beam (the so called pump laser) onto a small spot on the surface and detecting the emitted light. In order to scan the surface we want to install moveable mirrors deflecting the laser beam. The mirrors are already installed in our lab. Your task will be implementing LabVIEW based software that controls the mirrors and thus the deflection of the beam. Together with us you will build a simple optical setup and investigate its performance. Experience with LabView is definitely an advantage in this project.

After the project you will:

- Have basic knowledge about physics behind distributed feedback dye lasers

- Have experience with characterizing the lasers and working in our optics lab

- Have increased your knowledge about LabView and its use for scanning mirror control
