A quantum phonon bus for diluted spins interaction

• 2022 — 2023

We design the compact SiC OMC cavity to enhance the phonon/photon interaction with the divacancy. Owing to the strong confinement of the phononic mode, a strong coupling between phonon and spins is expected. Based on this device scheme, the phonon can be used as the channel to entangle multiple spins regardless of the spin-spin spacing and inhomogeneity. Those results pave the route to further scale up the quantum computing based on solid-state spin systems.

Engineering of the tunable quantum phonon states in strained 2D quantum dots

• 2021 — 2022

We engineer the local strain to achieve the site-control of the quantum emitter in bilayer WSe2. Owing to the perpendicular dipole moment of the localized interlayer exciton, the emission energy is highly tunable and quantum phonon cascades of quantum emitters are investigated. Also, we are working on the integration of the photonic crystal waveguide to study the collective behaviors of the multiple single-photon emitters.

Transport of 2D exciton with acoustic wave

• 2019 — 2021

We achieve the directional transport of the exciton by the surface acoustic wave (SAW). The SAW on bulk LiNbO3 can interact with the exciton and carry the exciton with a long propagation distance. Also, the exciton behaviors at different regimes have been observed. Our work shows that acoustic waves are an effective, contact-free means to control exciton dynamics and transport, promising for realizing 2D materials-based excitonic devices such as exciton transistors, switches, and transducers.

Remotely programmable black phosphorus phototransistor array for broadband optoelectronic edge computing

• 2020 — 2021

We construct a hybrid-dimension heterostructure device by 2D black Phosphorus and 3D AlOx/HfOx/AlOx stack to achieve optoelectronic computing. The tasks of the artificial neural network like pattern recognition and edge detection have been demonstrated.

Separation of the valley exciton-polariton with anisotropic photonic crystal

• 2018 — 2019

We propose an approach to separate valley exciton-polariton with the engineering of the symmetry of the photonic structure, a Rashba-type splitting of polariton dispersion is theoretically predicted.

Black Phosphorus modulator and photodetector for mid-infrared applications

• 2015 — 2018

We utilize the strong interlayer coupling of the black Phosphorus (bP), and prototypes of modulator and photodetector based on bP thin films have been demonstrated.

Nanofabrication

I have several years of experience in the cleanroom with a strong expertise in most of the cleanroom facilties such as Ebeam lithography, Photolithography, RIE-ICP etching, Ebeam evaporation, Chemical-mechanical polishing, Wire-bonding, etc. I have successfully fabricated the integrated photonic devices with high Q factor in Si, SiNx, GaP platforms.

Designing and modeling photonics

I have developed strong expertise in the multiphysics simulation including COMSOL (FEM), ANSYS (FEM), Lumerical (FDTD).

Experience with silicon photonic test flows

I have built the fiber-array setup for the fast chateraterization of the Si photonic chips with the ability to test 16 ports of the integrated photonic chips (eg. Setup for the optical computing, integrated optical isolator, modulator, detector).

Python and labview tools for operating multi-instrument and multi-computer laboratory experiments

I have worked with Labview and python tools such as Qudi and Pi3Diamond (Pi3) to perform the measurement such as characterizing integrated photonics, optoelectronic edge computing, scanning NV probe, and confocal mapping of spin qubits.

Softwares

I am familiar with the softwares including Python, Labview, Matlab, Mathematica, 3Ds Max, etc.
