Hybrid Optomechanical Technologies

We are now part of a joint academic – industry consortium to work on hybrid optomechanical technologies (HOT).

HOT is a Horizon 2020 network bringing together 13 European universities and 4 companies (IBM, STMicroelectronics, Hitachi, Thales) to lay the foundations for a new generation of nanoscale devices. A particular focus will be on high efficiency electro-optomechanical systems that bridge microwave and photonic energy scales using mechanical transduction.

The European Union funds HOT with 10M as part of the Horizon 2020 initiative FET Proactive.

Cooling a dielectric mechanical oscillator to its quantum ground state

Screen Shot 2016-08-03 at 10.44.31 PMPreparation and detection of mechanical objects at the quantum zero-point level has been achieved in both the optical and microwave regimes. Here, the authors develop silicon nitride nanomembranes that are suitable for integrating nanophotonic, nanomechanical and superconducting microwave circuits together.

New silicon platform for cavity-electromechanics

PhysRevApplied.6.014013The coupling of electromagnetic fields to nanomechanical systems has ushered in the field of quantum optomechanics, in which vibrating objects can be studied and used at the level of their quantum zero-point motion. The authors fabricate a planar technology platform for integrating nanophotonic, nanomechanical, and superconducting microwave circuits. Joining these components could yield a quantum converter between the microwave and optical frequency domains, enabling long-range networks of superconducting qubits for quantum information processing.

Electro-optical wavelength conversion

michele_EOMLinking classical microwave electrical circuits to the optical telecommunication band is at the core of modern communication. Future quantum information networks will require coherent microwave-to-optical conversion to link electronic quantum processors and memories via low-loss optical telecommunication networks. Efficient conversion can be achieved with electro-optical modulators operating at the single microwave photon level.

In the current issue of Optica we present a comparably high bandwidth converter operating at room temperature:

Call for IST Fellows

Excellent candidates who are interested in our research are encouraged to apply for the ISTfellow program. Our group is looking for researchers with experience in at least one of these areas: superconducting circuits, low temperature physics, electromechanics and micro- and nano-fabrication.

The next application deadline for the ISTfellow program is March 15th, 2016.
