Yu Research Group
Researchers in the Yu group are exploring basic physics processes in optics and optical materials, and applying acquired knowledge to the development of novel materials, devices, and biomedical imaging system. For example, we are developing photorefractive multiple quantum wells for coherence domain biomedical imaging. The technique, so called holographic optical coherence imaging (OCI), uses dynamic holography based on the photorefractive effect. This project has been funded by National Science Foundation as the Faculty Early Career Development (CAREER) Award.
Another biomedical imaging project we are working with is fluorescence mediated tomography based on the heterodyne method and the development of site-specific fluorescent peptides. The project will develop techniques and probes for early detection of breast and prostate cancers. The project is founded by National Institute of Health.
We are also working on semiconductor optics and nonlinear optics, including electric coupling in vertically coupled quantum dots, characterization of UV ZnO devices and second harmonic generation and third harmonic generation of organic and inorganic materials.
