Haoning Tang, PhD

Tang Lab Main Mission

Welcome! My name is Haoning Tang and I am a Research Associate at Harvard University. I received a Ph.D. (2021) in Applied Physics from Harvard University and a B.Eng. in Electrical Engineering and Computer Science from the Hong Kong University of Science and Technology (HKUST) in 2016.

I'm the recipient of SONY faculty innovation award in 2025, the Rising Star of Light Award in 2024, Harvard Quantum Initiative (HQI) Fellowship in 2021, and Harvard Hong Kong Jockey Club Fellowship in 2017.

I'm a 70% experimentalist and 30% theorist. My research covers a wide variety of topics ranging from nanophotonics, quantum materials, optical metamaterials, nonlinear and quantum optics, micro(nano)electromechanical systems (MEMS), integrated photonics, nanotechnology and nanofabrication, and nanophotonic devices, and their applications to the development of novel light sources, detectors, and photonic integrated systems. You can learn more about my research in the Research section. A list of my published work can be found on the Publications page. This website also contains general information on my work and publications. See the About Me section for my contact information.

My future group/lab will work on research that includes interdisciplinary topics in material science, nanophotonics, and devices. This will include:

In situ tuning of the mechanical, electrical, and optical properties of single/multilayer quantum materials, thin films, and metamaterials:
- Twist angle, interlayer gap, translational distance, pressure and pressure gradient, strain
- Gating voltage
- Nonlinear index
MEMS for probing the material properties and sensing:
- Force & strain sensing
- Hyperimaging, high-dimensional sensor
Engineering of hyper-reconfigurable light sources—giant nonlinearity, tunable entanglement source, tunable single emitters, and tunable lasers.
Controllable strong light-matter interaction through cavity enhancement and thin film strain tuning.
Meta-optic high-dimensional sensors and multidimensional modulators.

My skill sets are:

Nanofabrication : Metamaterials; 2D materials; MEMS; Photonic integrated circuits
Optical measurement: Free-space optics; Integrated photonics; Nonlinear/quantum optics; Ultra-fast
Optical theory and computation: optical metamaterials
