Optomechanical Coupling in a Two-Dimensional Photonic Crystal Defect Cavity

Tobias Kippenberg, Emanuel Gavartin

Periodically structured materials can sustain both optical and mechanical modes. Here we investigate and observe experimentally the optomechanical properties of a conventional two-dimensional suspended photonic crystal defect cavity with a mode volume of s ...

Octave Spanning Tunable Frequency Comb from a Microresonator

Tobias Kippenberg, Tobias Herr, Emanuel Gavartin

We report the generation of an octave-spanning optical frequency comb in a continuous wave laser pumped microresonator. The generated comb spectrum covers the wavelength range from 990 to 2170 nm without relying on additional external broadening. Continuou ...

Measuring nanomechanical motion with an imprecision below the standard quantum limit

Tobias Kippenberg, Emanuel Gavartin

We report a room-temperature measurement of nanomechanical motion with an imprecision below the standard quantum limit (SQL), using cavity-enhanced optical near fields. Fundamental thermodynamical cavity frequency fluctuation limits the total imprecision t ...

Optomechanically Induced Transparency

Tobias Kippenberg, Albert Schliesser, Emanuel Gavartin, Stefan Alexander Weis

Electromagnetically induced transparency is a quantum interference effect observed in atoms and molecules, in which the optical response of an atomic medium is controlled by an electromagnetic field. We demonstrated a form of induced transparency enabled b ...
