Research Areas

  • Passive Optical Communication and Localization

Similar to RFID, optical communication can also be operated in passive mode. By utilizing light retroreflection, a visible light backscattering (VLB) tag harvests energy using solar cell and modulates the reflected light beam from retroreflector by shutters (i.e. liquid crystal display (LCD) shutter). Unlike RF-based backscattering technologies, VLB does not suffer from multipath effect; does not need dedicated reader placed in vicinity; does not introduce inter-channel interference; does not interfere with RF sensitive devices. In this research, I aim to apply the VLB technique in an energy-efficient and spectrum-efficient manner to enable joint communication and localization for a wide range of applications such as health monitoring, connected vehicles, underwater communication as well as accurate and ubiquitous indoor localization.
