Technology Expertise
Ms. Du has expertise in computer networking, optoelectronic devices and systems.
As a research assistant at the UC Davis, she conducted theoretical research on optoelectronic devices for optical communication with an emphasis on optical CDMA. She designed and characterized arrayed waveguide grating (AWG) and Mach-Zehnder interferometer (MZI) integrated photonic devices.

In addition, she conducted experiments at the sub-system level for non-linear thresholding in optical CDMA, and performed numerical simulation with MATLAB to evaluate the network performance of spectral-encoded time-spread optical CDMA.

Publications And Patents
Ms. Du is the author or coauthor of more than 20 conference and journal articles documenting research in light scattering spectroscopy, optoelectronic devices and optical-CDMA technologies.

For her doctoral dissertation, Ms. Du examined the influence of a non-linear optical thresholder on high-performance optical CDMA networks.

At Oklahoma State University, she studied velocity difference measurements using a fiber-optic coupler for her master’s degree thesis.
Photo-acoustics and its application in Quantitative Nondestructive Evaluation (QNDE) of semiconductor materials composed her baccalaureate research topic.
