Prior to joining NCSU in 2004, he spent two years with the functional-polymers group at Eindhoven University of Technology (the Netherlands) as a post-doctoral fellow. His PhD research at Brown University on organic electro-optical materials and their use in photonics and flat-panel displays has been recognized by the International Liquid Crystal Society (ILCS) with the Glenn H. Brown Award (2004) and by the Optical Society of America with the OSA/New Focus Student Award (2002) at the CLEO/QELS Conference. He continues to pursue interdisciplinary research topics in photonics, organic electronics, optics, biophotonics, and flat-panel displays.
Nanoelectronics and Photonics
My primary goal with OLEG is to innovate technologies that enable the efficient control of light over intensity, direction, and polarization for various applications including displays, polarimetry, optical communications, biomedical imaging, and so on. To this end, we utilize liquid crystal polarization gratings (LCPGs) that can modulate unpolarized (natural) light or convert the polarization state of light at ~100% efficiency. My research focuses on designing and fabricating high quality LCPGs with advanced properties (i.e., broadband, fast-switching, high polarization-contrast, etc). To investigate diffraction behaviors of LCPGs, we apply our in-house optical simulation tool WOLFSIM as well as the Jones matrix analysis. Along with rigorous modeling, experimental studies will follow mainly with liquid crystals and LC alignment materials. We also explore fabrication technologies that are feasible for practical applications (i.e., low cost, compact, high yield, commercially available materials). Our approach is patterning the grating profile in photoalignment materials by holographic recording and amplifying the grating structure by aligning liquid crystals from the surface. We are developing fabrication processes for high quality LCPGs by optimizing grating parameters and materials. My research also includes to explore possible/promising applications where we can maximize benefits from unique properties of LCPGs.
