The Jokerst Research Group at Duke University is part of the Department of Electrical and Computer Engineering and the Fitzpatrick Institute of Photonics. The Jokerst Group focuses on chip-scale optical sources for optical sensing systems, such as portable medical diagnositcs, and environmental monitoring. The technology areas include expertise in optical system design, optoelectronic device and system design, photonic materials and devices, and fabrication of semiconductor devices. Our current primary research areas of interest include chip-scale photonic sensing systems, III-V thin-film lasers integrated onto silicon, integrated optoelectronics, optoelectronic devices, metamaterials and integrated plasmonics, and optical interconnects.
