The Advanced Photonics Research Group, led by Assoc. Prof. Nguyen Hoang Hai, focuses on the design, simulation, and development of next-generation optical and photonic devices. The group’s research is centered around Photonic Crystal Fibers (PCF), metamaterials, and two-dimensional (2D) materials such as Graphene, VO₂, MoS₂, and BlueP/WSe₂.Main research directions include:Development of highly sensitive Surface Plasmon Resonance (SPR) sensors for biomedical, environmental, and industrial applications. Design of multifunctional terahertz (THz) absorbers and graphene-based hyperbolic metamaterials for advanced optical sensing, security, and energy harvesting. Integration of metamaterials with Substrate Integrated Waveguide (SIW) technology for high-speed wireless communication and antenna systems. Application of artificial intelligence and numerical modeling tools (FDTD, COMSOL) to optimize optical device performance and predict material behavior. The group aims to bridge fundamental research and practical applications, advancing the development of compact, multifunctional, and smart optical sensors and amplifiers suitable for Lab-on-Chip and photonic integrated systems. With a long-term vision to become a regional leader in photonic sensing and 2D material research, the group actively promotes international collaborations, graduate training, and innovative research that supports the emerging fields of 5G/6G optical communication and the Photonic Internet of Things (P-IoT).
