Optomechanical Spin-Photon Interface in Wide-Bandgap Materials
… quantum memories and 'flying' photonic qubits at telecommunication wavelengths. Hybrid mechanical systems aim to overcome this challenge by harnessing the ability of mechanical motion to control and couple disparate quantum systems. In recent years, experiments have demonstrated mechanical control …

Advanced light manipulation and waveguiding in plasmonic nanostructured optical fibers.
… beam milling technique. Highly polarization- and wavelength-dependent transmission with transmission efficiency ~ 70 % in the telecommunication wavelength observed by launching light into two orthogonal linear polarization states of the fiber. In the second project, I have extended the use of the …
