Remarkable optical properties of atomically thin 2D materials are widely tunable by doping, strain, and external fields, owing to their atomic thickness and unique characteristics. We are investigating the exciton dynamics in monolayer transition metal dichalcogenides (TMDs) and those heterostructures. 

2D materials hold great promise for new optoelectronic devices. In addition, the ability to create layered vdW heterostructures using those 2D materials enables assembly of more complex optoelectronic devices. We fabricate manufacture various optoelectronic devices such as LED, Laser, and PD.

Photonic integrated circuits (PIC) could further enhance system performance and data handling capacities, while enabling new possibilities in spectroscopic sensing through the heterogenous integration of diverse optical materials including III-V semiconductors, QDs, 2D materials, and complex oxides, etc.

It is easy to implant 2D materials on Si photonics without complications arising from lattice mismatch or fabrication processes. 2D materials can be fabricated into active components to realize a diverse amount of applications, as integrated into Si photonics. 

We are working to integrate the core functions based on 2D materials, including photon emitting, qubit generating, no-loss modulations, detections, and photonic memory, into Si photonic systems to realize photonic quantum processing system.
