Mingliang Xiong (熊明亮)

I am currently an Assistant Professor at Tongji University. Prior to this, I was a Research Fellow at the National Institute of Extremely-Weak Magnetic Field Infrastructure in Hangzhou, China (2022-2024). I received the Ph.D. degree from Tongji University, Shanghai, in 2022, and the B.Eng. degree from Nanjing University of Posts and Telecommunications, Nanjing, in 2017. My research focuses on solid-state lasers, self-aligned/alignment-free lasers (spatially-distributed cavity lasers), mobile optical wireless communications and power transfer, and the Internet of Things. My publications have appeared in journals such as IEEE TWC, IEEE COMMAG, IEEE TCOM, and IEEE IoT Journal. I have been awarded the Phoenix Contact Scholarship in 2018, National Scholarship in 2020, Huawei Scholarship in 2021, and the Pursuing Excellence Scholarship (Tongji University's highest honor for student) in 2023.

Recent Research

  • Mobile Wireless Charging Using Self-aligned Resonant Laser Beam

    • We developed an experiment on a self-aligned resonant beam charging system for long-distance mobile power transfer. It exploits light resonances inside a double-retroreflector-based spatially separated laser resonator (SSLR), which eliminates the requirement for any kind of tracking control. The experimental results show that above 5-W optical power (also obtained more than 0.6-W electrical power) transferring with negligible diffraction loss to a few-centimeter-size receiver is realized while the receiver moves arbitrarily within 2-m vertical distance and 6◦ field of view from the transmitter. The maximum horizontal moving range is up to ±18 cm. This wireless charging system empowers a smartphone in mobile operation with unlimited battery life without the need for a cable.

  • Mobile Optical Communications/SWIPT Using Resonant Laser Beam

    • Optical wireless communications (OWC) utilizing infrared or visible light as the carrier attracts great attention in 6G research. Resonant beam communications (RBCom) is an OWC technology which simultaneously satisfies the needs of non-mechanical mobility and high signal-to-noise ratio (SNR). It has the self-alignment feature and therefore avoids positioning and pointing operations. However, RBCom undergoes echo interference. Here we propose an echo-interference-free RBCom system design based on second harmonic generation. The transmitter and the receiver constitute a spatially separated laser resonator, in which the retro-reflective resonant beam is formed and tracks the receiver automatically. This structure provides the channel with adaptive capability in beamforming and alignment, which is similar to the concept of intelligent reflecting surface (IRS) enhanced communications, but without hardware and software controllers. Besides, we establish an analytical model to evaluate the beam radius, the beam power, and the channel capacity. The analysis results show that our system achieves longer distance and smaller beam diameter for the transmission beyond 10 Gbit/s, compared with the existing OWC technologies.
