Abstract

We are entering a post-smartphone era, where zillions of new wireless devices compete for the already limited radio spectrum (RF) to obtain wireless connectivity. Addressing the problem of spectrum crunch demands radical new thinking. In this talk, I will present our journey in exploring light as a new spectrum territory, which provides ten thousand times wider bandwidth than RF for wireless communication. Additionally, the physical properties of light offer unique benefits for object tracking and behavioral sensing. I will highlight two recent works as examples on light-based communication and sensing. The first work exploits laser light to enable bi-directional, high-bandwidth air-water communication to facilitate underwater robotic operations. The second work advances light sensing to enable noninvasive glucose sensing for diabetic patients using portable, low-cost, and off-the-shelf hardware. I will conclude with open challenges and ongoing work.
