A vertically-loaded diamond microdisk resonator spin-photon interface

نویسندگان

چکیده

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 0.33. As design is compatible established nanofabrication techniques couples low-NA modes accessible by cryogenic optical systems, it promising platform interfaces based on quantum emitters.

Silicon carbide microdisk resonator.

We demonstrate a silicon carbide (SiC) microdisk resonator with an intrinsic optical quality factor of 6.19×10(3), fabricated on the 3C-SiC-on-Si platform. We characterize the temperature dependence of the cavity resonance and obtain a thermo-optic coefficient of 2.92×10(-5)/K for 3C-SiC. Our simulations show that the device exhibits great potential for cavity optomechanical applications.

Spin-photon interface and spin-controlled photon switching in a nanobeam waveguide.

The spin of an electron is a promising memory state and qubit. Connecting spin states that are spatially far apart will enable quantum nodes and quantum networks based on the electron spin. Towards this goal, an integrated spin-photon interface would be a major leap forward as it combines the memory capability of a single spin with the efficient transfer of information by photons. Here, we demo...

Adiabatic self-tuning in a silicon microdisk optical resonator.

We demonstrate a method for adiabatically self-tuning a silicon microdisk resonator. This mechanism is not only able to sensitively probe the fast nonlinear cavity dynamics, but also provides various optical functionalities like pulse compression, shaping, and tunable time delay.
