• SLO technology now allows real time visualization of retinal cones without adaptive optics
  • Intrasurgical OCT allows tracking of surgical tools in real-time during sugery
  • New SIM technology doubles imaging resolution beyond diffraction limit in nonfluorescent samples
  • Coherence revival allows complete complex conjugate removal and doubles OCT penetration depth
  • Handheld, rapidly switchable, anterior and posterior segment visualization possible now with SSOCT


The Biophotonics Group is directed by Professor Joseph Izatt and is located in the Fitzpatrick Center for Interdisciplinary Engineering and Applied Sciences (FCIEMAS) in Duke University. The laboratory is part of the Fitzpatrick Institute of Photonics (FIP) and the Biomedical Engineering Department within Duke's Pratt School of Engineering.

The Biophotonics Group is concerned with the application of cutting-edge optoelectronic technologies to problems in the biomedical sciences. Its research centers on the utilization of optical technologies for non-invasive, high-resolution imaging and sensing in living biological tissues. The technologies used in this laboratory include acousto-optic and integrated-optic devices, femtosecond lasers, custom optomechanical designs, and ultrabroadband fiber optic telecommunications equipment. To develop practical solutions in clinical ophthalmology, the lab maintains close connections with the Duke Eye Center and promotes active collaborations between its engineers and their clinicians.
