Impurities in diamond are one of the most promising qubits for quantum information processing. They have been used already in proof-of-principle quantum optics experiments, and if they can be incorporated into nanophotonic devices it will be possible to build practical quantum technologies, e.g. for quantum computing and networking. Our lab is creating the photonic technology…
We have recently demontrated nanocavity optomechanical devices based on silicon photonics which can detect sources of torque with unprecedented sensitivity. These structures are currently being used to probe nanomagnetic phenomena and demomstrate magnetic field sensors with unique combination of spatial resolution, sensitivity and dynamic range. Several projects are building on this success: creating sensors for detecting optical angular momentum…
2D materials, the most famous of which is graphene, are promising for sensing and quantum technology. Hexagonal boron nitride (hBN) is a layered 2D material that is exciting thanks to its ability to host quantum emitters / single photon sources. By combining hBN with silicon photonic devices, we recently demonstrated the very first cavity optomechanical system with…
