Danqing Wang

Danqing Wang's research spans the intersection of nanomaterials, photonics, and quantum systems.

She has achieved numerous breakthroughs in nanolaser research. Through the design of a multiscale superlattice structure, she pioneered the color-controllable output of multimode lasers in a single device, providing new solutions for multicolor bioimaging and multiplexed optical communications. Inspired by nature, her development of a mechanically tunable nanolaser lays a solid foundation for future flexible displays and wearable sensing. Furthermore, the ultra-low threshold, highly photostable upconversion nanolaser she co-developed has expanded the application of nanolasers to in vivo imaging and quantum sensing.

Concurrently, she pioneered the new direction of epsilon-near-zero (ENZ) optics. She was the first to introduce an analogy of the "proximity effect" from superconductivity into optical systems, enabling precise manipulation of ENZ material properties using transparent oxide semiconductors. She demonstrated that ENZ thin films can serve as low-loss, defect-tolerant optical claddings and discovered an ultra-long-range optical coupling phenomenon, offering new approaches to addressing crosstalk and loss challenges in photonic integrated circuits and developing novel quantum simulation platforms.

With these innovative contributions, Danqing Wang is leading the construction of large-scale nanophotonics platforms, paving new paths for next-generation integrated photonics and quantum engineering.
