About

Michikazu Hattori is a leading researcher in high-speed free-space optical (FSO) communications, with a focus on enabling robust, mobile, and ultra-high-capacity wireless links. His major contributions center on overcoming the fundamental challenge of beam misalignment in mobile FSO systems. Hattori pioneered the integration of a three-stage high-speed optical beam stabilizer with a two-dimensional photodetector array (2D-PDA) and maximum-ratio combining digital signal processing. This innovative approach achieves spatial diversity reception, effectively mitigating signal fading caused by transmitter movement and atmospheric turbulence. His experimental work has demonstrated a landmark 40-Gbit/s PAM-4 mobile FSO link over a 2.1-meter line-of-sight, supporting a zigzag-moving transmitter at 400 mm/s—a critical step toward practical deployment in support robots and autonomous systems. With his most-cited papers already garnering attention in the field, Hattori’s research pushes the boundaries of wireless connectivity, promising to deliver fiber-like speeds to mobile platforms. His work is pivotal for next-generation applications requiring high-bandwidth, low-latency links in dynamic environments.
