Optomechanics of coupled micro-drums
In this project you will dive into the interesting field of cavity optomechanics. We create micrometer-scale mechanical devices made from silicon nitride using advanced nanofabrication techniques here on campus: imagine a drum, but now more than 10 000x smaller! So small that it can be played ustilizing the momentum of photons, the so-called radiation pressure. You will also use light to extract information about mechanical properies - like their quality factors and resonance frequencies and even see their eigenmodes. What happens to these properties when many of the drums are coupled? That will be the key question of your project. We apply a novel technique to perform usually very long measurements on rather short time scales. We already have some working samples, so you can directly start and go ahead with the measurements. But you will also have the chance to learn many aspects of nanofabrication and make your own devices in the cleanroom, then measure them, and analyze the data.
