Joe Charles Campbell is the Lucien Carr III Professor of Electrical and Computer Engineering at the University of Virginia. Previously, he held the Cockrell Family Regents Chair in Engineering at the University of Texas at Austin (1989–2006). His research focuses on optoelectronic devices, particularly high-performance photodetectors for fiber optics communications, including avalanche photodiodes (APDs), Si-based optoelectronics, and mid-infrared detection technologies. He has authored over 400 journal articles and 400 conference presentations, with notable contributions to low-noise avalanche photodiodes and material innovations like AlInAsSb alloys. His work emphasizes high-speed, low-noise, and radiation-tolerant photodetection systems.
Education: B.S. Physics (University of Texas at Austin, 1969), M.S. and Ph.D. Physics (University of Illinois at Urbana-Champaign, 1971 and 1973). Postdoctoral research at University of Illinois (1973–1974). Early career included roles at Texas Instruments (integrated optics) and AT&T Bell Labs (optoelectronic devices).
Research Highlights:
- Development of AlInAsSb-based APDs for single-photon counting and mid-infrared detection.
- Advances in high-power, high-linearity photodiodes and flip-chip bonded designs for thermal dissipation.
- Pioneering work in staircase avalanche photodiodes with optimized excess noise characteristics.
Awards & Recognition:
- Member of the National Academy of Engineering (2002).
- Lucien Carr III Professorship (University of Virginia).
Labs & Teams: Leads the Photonic Devices Group at UVA, focusing on optoelectronic materials and device fabrication. Collaborates on radiation-tolerant photodetectors and integrated photonic platforms.
