Here, we demonstrate purely dispersive coupling of high-Q nanomechanical oscillators to an ultrahigh-finesse optical microresonator via its evanescent field, extending cavity optomechanics to nanomechanical oscillators. Dynamical backaction mediated by the optical dipole force is observed, leading to laser-like coherent nanomechanical oscillations solely due to radiation pressure. Moreover, sub-fm Hz−1/2 displacement sensitivity is achieved, with a measurement imprecision equal to the standard quantum limit (SQL), which coincides with the nanomechanical oscillator’s zero-point fluctuations. The achievement of an imprecision at the SQL and radiation-pressure dynamical backaction for nanomechanical oscillators may have implications not only for detecting quantum phenomena in mechanical systems, but also for a variety of other precision experiments. Owing to the flexibility of the near-field coupling platform, it can be readily extended to a diverse set of nanomechanical oscillators. In addition, the approach provides a route to experiments where radiation-pressure quantum backaction dominates at room temperature, enabling ponderomotive squeezing or quantum non-demolition measurements.</dcterms:abstract> <dc:creator>Unterreithmeier, Quirin P.</dc:creator> <dc:creator>Anetsberger, Georg</dc:creator> <dc:contributor>Weig, Eva M.</dc:contributor> <dc:contributor>Arcizet, Olivier</dc:contributor> <dc:creator>Arcizet, Olivier</dc:creator> <dc:contributor>Anetsberger, Georg</dc:contributor> <dcterms:rights rdf:resource=""/> <dc:creator>Weig, Eva M.</dc:creator> <dc:language>eng</dc:language> <dc:creator>Kippenberg, Tobias J.</dc:creator> <dc:contributor>Kippenberg, Tobias J.</dc:contributor> <dcterms:bibliographicCitation>Nature Physics ; 5 (2009), 12. - S. 909-914</dcterms:bibliographicCitation> <dcterms:hasPart rdf:resource=""/> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> <dc:contributor>Rivière, Rémi</dc:contributor> <dc:creator>Rivière, Rémi</dc:creator> <dcterms:available rdf:datatype="">2013-06-06T08:43:30Z</dcterms:available> <bibo:uri rdf:resource=""/> <dspace:isPartOfCollection rdf:resource=""/> <dspace:hasBitstream rdf:resource=""/> <dc:rights>terms-of-use</dc:rights> </rdf:Description> </rdf:RDF>
