We explore new science and technologies on nano-structured optoelectronic devices for applications in ultrahigh-speed communications for data centers and 6G backbones, bio/medical diagnosis silicon phontonic chips, ultra bright CMOS image sensors, and next generation LiDAR sensors. We are equipped with nano-photonics theory, numerical simulation codes/tools/methodologies, epitaxy designs, clean-room fabrication technologies, and advanced characterization set-ups.
