Welcome to Microcavity Group!
Optical micro-cavity and nanostructure group is focusing on integrated optical quantum information techniques. Such an optical chip with integrated photons source from single quantum dot emission or nonlinear optical process in nanostructure, high efficient quantum operations based on photon-photon interaction in micro-cavity, and Surface Plasmon assisted transmission, filter, and detection will be applied as the basic units for quantum internet and future quantum simulations.
Integrated optical quantum information techniques show higher stability, higher fidelity, and lower power consumption than free space linear optical techniques. Along with the photon-atom interaction with micro-cavity QED, quantum two-qubit operation with nonlinear interaction between photons shows overwhelming advantages over those linear optical operations based on photon interference. More important, the fabrication can be well transplanted from with mature traditional integrated optical techniques.
Main topics:
1. Photon source:
Single photons from single quantum dot or NV center in diamond with the interaction with micro-cavity, nano-wire or metal surface Plasmon; Two photons from micro-cavity parametric down conversion;
2. Transmission and linear optical operation;
On-chip interferometer with optical waveguides and nano-wires; Surface Plasmon assisted polarization operations;Optical filters with micro-cavity;
3. Photon-photon interaction with micro-cavity QED:
Fabrication of micro-cavity with diamond, silica, and other materials;
Fabrication of NV centers in diamond;
Manipulation of spin level in NV center with optics and micro-wave;
4. Detection |
