Research

The group's main research theme focuses on novel materials and devices to exploit interactions of light with matter. Our work covers a wide spectrum of applications including:

  1. On-chip sensing and spectroscopy: capitalizing on a digital Fourier-Transform (dFT) technology the group invented, we have created miniaturized and rugged sensors that can be mass produced using standard CMOS manufacturing technologies for industrial process control, medical imaging, and space applications.
  2. Optical phase change materials and meta-optics: optical phase change materials are a class of materials whose optical properties are drastically modified upon undergoing a solid-state phase transition. Using these intriguing materials, the group have pioneered a series of cutting-edge reconfigurable optical devices that can be re-programmed to adapt to specific tasks.
  3. 2-D material photonic integration: 2-D materials offer many tantalizing properties that conventional optical materials do not possess. However, integration of these materials onto an integrated photonics platform can be challenging. Our group's work helps to address the challenge by developing new monolithic integration schemes on 2-D materials, enabling novel photonic devices with unprecedented performance.
  4. Flexible photonics and polymer photonics: traditionally, photonic circuits are fabricated on rigid substrates such as semiconductors or glasses. The group have developed novel methods to make photonic devices flexible, stretchable and rugged without compromising their optical performance. We are exploring emerging applications of such devices in biomedical monitoring and high-speed data communications.
  5. Optics for solar energy: we have demonstrated novel optical architectures and module integration technologies that can effectively boost the efficiency of photovoltaic modules while maintaining a footprint and cost comparable to standard silicon flat panels.
  6. Magneto-optical isolation: we are developing chip-scale one-way valves for photons that will become an integral part of next-generation optical communication and navigation systems.
