Current research topic

The objective of the project is to develop novel, compact optomechanical nanoresonators, based on photonic crystals slab resonators. Such resonators are capable of providing large band reflectivity and, in a different geometry, of tightly confining light in a small mode volume. We will develop these platforms in different material systems, ranging from III-V semiconductors to diamond. In particular, photonic crystal reflectors will be employed as deformable mirror in an interferometric setup. Mechanical vibrations of photonic crystal cavities suspended on an optical waveguide defined on a semiconductor substrate are also under investigation. By evanescently coupling a laser into the photonic crystal cavity through the access waveguide, the brownian motion of the suspended photonic crystal membrane can be read out, providing potentially access both to drum modes of the full membrane and to vibration modes localised within the photonic crystal cavity.
