Welcome to professor Wang Qijie’s research group in School of Electrical and Electronic Engineering, and School of Physical and Mathematical Sciences, Nanyang Technological University, Singapore.

The main interests of our research are broadly in optoelectronic technologies from fundamental studies to various applications, specifically on investigating theoretically and experimentally fundamental light-matter interactions in the infrared regimes in new materials and new designs, and developing novel photonic and optoelectronic devices and systems.

Most of the spectrum windows in the electromagnetic spectrum have been well developed, leading to important applications that have changed our life significantly. However, the mid- and far-infrared (Terahertz) regime, ~3-300 micrometer, still remains the least developed spectrum window mainly due to the lack of compact, electrically-driven, high performance photonic and optoelectronic devices. This region is called the molecular fingerprint region, as molecules have unique and strong absorption features which are related to the vibration modes of oscillations. Thus, obtaining such high performance photonic/optoelectronic devices and systems in this region could enable a broad range of applications including but not limited to sensing & spectroscopy, biomedical sciences, communications, quality control of food, environmental monitoring and process control, imaging and security screening, defense, etc.

In particular, we are developing innovative 
1) Mid- and far-infrared lasers, particularly quantum cascade lasers; 
2) 2D material based mid-IR and THz optoelectronic devices (waveguides, detectors, and modulators), and 
3) Infrared plasmonic and metamaterial devices.

We are always looking for strongly motivated both postdoc and Ph.D researchers dedicated to the cutting edge research in laser physics and engineering, nanotechnology, and nano-optics/photonics. Interested candidates please send your CV to qjwang@ntu.edu.sg. Shortlisted candidates will be contacted.
