Integrating optically active III-V materials on silicon/insulator platforms is one potential path towards improving the energy efficiency and performance of modern computing. Here we demonstrate applicability direct wafer bonding combined with plasma etching to fabrication complex nanophotonic systems out InP layers. We explore optimise InP, validating existing processes developing improved one...

We propose and optimize a vertically-loaded diamond microdisk resonator (VLDMoRt) coupled to nitrogen-vacancy (NV) center in for efficient collection of zero-phonon-line emission into low numerical aperture ($\text{NA}$) free-space modes. The VLDMoRt achieves Purcell enhancement 172 with $39\%$ the emitted light collected within $\text{NA}$ 0.6, leading total external spin-photon efficiency 0.3...

In this paper, optical properties of coupled silica disk microresonators are investigated. The spectral response and the light intensity distribution along the coupled disks were measured. It was found that the distribution depends on the particular excited resonance, which can be attributed to the formation of normal modes of the coupled resonator system. A developed theoretical model gives qu...

We demonstrate a C-band wavelength-tunable microlaser with an Er3+ doped high quality (~1.02x10^6) lithium niobate microdisk resonator. With 976 nm continuous-wave pump laser, lasing action can be observed at power threshold as low ~250 {\mu}W room temperature. Furthermore, the laser wavelength tuned by varying power, showing tuning efficiency of ~-17.03 pm/mW blow 13 mW, and 10.58 above mW.
