      "summary_nl": "The coupling between light and mechanical motion through radiation pressure enables both fundamental experimental research into the quantum behavior of macroscopic objects as well as new technological applications such as light-actuated high-frequency resonators. Crucial to both is the realization of strong optomechanical coupling. We propose to develop novel optomechanical systems that exhibit ultrastrong interactions between light and motion to achieve cooling of a mechanical oscillator to the quantum ground state of motion and to demonstrate new optomechanical functionality. Small silica toroidal cavities supported by 'spokes' serve as optical and mechanical resonators at the same time. They will be used to demonstrate ground state cooling. Moreover, we will use two-dimensional photonic crystal cavities in which phononic and photonic modes are highly co-localized to achieve ultrastrong coupling between a cavity mode and high-frequency mechanical oscillations. These systems can perform as all-optically tunable GHz oscillators, with applications in wireless communications technology, photonics and ultrasensitive force detection.\n\nThe applicant, Ewold Verhagen, performed his PhD research at the FOM Institute for Atomic and Molecular Physics in Amsterdam, The Netherlands, in the field of nanophotonics. The host is the Laboratory of Photonics and Quantum Measurement at the EPFL in Lausanne, Switzerland, led by Tobias Kippenberg.\n",
