Abstract
Mechanical effects exerted by photons are generally considered to be too weak for real-world applications. The picture changes, however, when moving to nano-scale dimensions, at which considerable momentum transfer can result from photon bombardment. In this talk I will describe a chip-scale framework in which optical forces can be exploited as an efficient driving and sensing mechanism for nano-scale components. Besides allowing for unprecedented measurement sensitivity, such opto-mechanical interactions provide a new paradigm for coupling nano-mechanical and nano-photonic devices. I will provide an overview over progress on integrated opto-mechanics and also present recent results for chip-scale optical computing and mechanical data storage.
