Center of Optics and Optoelectronics (COO)
A group of electrical engineers, mechanical engineers, physicists and material scientists are working together at the Center in the photonics subareas of biomedical photonics, energy photonics and Information photonics
A group of electrical engineers, mechanical engineers, physicists and material scientists are working together at the Center in the following photonics subareas.
- Biomedical photonics. Currently, several faculty members are working closely to develop a multi modality biomedical imaging and sensing system. Our work is targeted at in vivo, wide field-of-view, high resolution imaging and high sensitivity, compact disease diagnosis, by employing state-of-the-art and creative technologies such as optical coherence tomography (Wu), focus grid scanning-based optical microscopy (Wu), photoacoustic microscopy (Chen), nonlinear optics (Wan), fiber-optical biosensing techniques (Li, Yang) and single molecule Raman spectroscopy (Yang).
- Energy photonics. Biomimetic surface textures are being employed in Yang’s lab on thin film inorganic and organic photovoltaic/LED devices to achieve higher efficiencies and lower costs.
- Information photonics. A variety of subjects are being explored in this category. By ultrahigh precision and portable optical sensing and coding techniques, long range, high resolution, high speed and multidimensional topography and pattern recognition are under investigation in Huang’s lab. Li works on on-chip photonics and fiber devices for communication and sensing. Yang works on nano lasers and photodetectors in light-wave circuits. Wan works on coherent absorbers, or the so called anti-lasers.
