Rochester Institute of Technology professor Jie Qiao is the general cochair of theinternational conference on Ultrafast Optics UFO X taking place in Beijing from Aug. 16 to21.
Ultrafast optics uses short optical pulses that can provide higher intensity than a continuouswave of light. Highenergy lasers can weld, cut and polish glass and other materials. Thetechnology enables integrated photonics and integrated optoelectronics—that combine orbond different materials. Ultrafast optics holds the potential to advance additivemanufacturing, or 3D printing, and freeform optics that go beyond traditional sphericalshapes.
“Optics is the enabling technology right now for cuttingedge research intelecommunication, energy, environmental sensing and optical displays,” said Qiao,associate professor in RIT’s Chester F. Carlson Center for Imaging Science. “Ultrafastlasers can transform the way optical components are being manufactured, leading to acosteffective, efficient and environmentally friendly solution for fabricating integratedphotonics, freeform optics, microoptics and optoelectronic packaging.”
Global interest in ultrafast optics has increased participation in the 10th internationalUltrafast Optics conference that Qiao helped organized. The biennial event is expected todraw 200 scientists from 20 countries. This year marks the first time the conference hasbeen held in China, which has a growing presence in optics research and development.
Qiao’s leadership role in the international conference and her presentation, “Ultrafastpolishing of siliconbased materials”—coauthored with RIT imaging science Ph.D. studentLauren Taylor—help put RIT on the map for ultrafast optics research and associatedtechnologies.
Qiao’s Advanced Optical Fabrication, Instrumentation and Metrology Laboratory at RIT’sCenter for Imaging Science produces fundamental research on theoretical modeling andexperimental demonstrations of ultrafast lasers and materials interaction. Her other lines ofresearch include an optical differentiation wavefront sensor for freeform metrology andphase imaging, and coherent phasing of segmented largescale gratings for nextgeneration telescopes or laser systems.
Qiao gained her reputation in the field of ultrafast optics in 2007 with landmark research atthe Laboratory for Laser Energetics at the University of Rochester, where she developed anefficient optical system that produced highenergy, picosecond pulses. Qiao used threehalfmeter segmented gratings—optical components that control the travel path of differentwavelengths of light—to compress highintensity lasers pulses in a segmented optical

system that works like a 1.5meter, continuous system. Her research appeared in the highimpact journals Optics Letters and Optics Express. Qiao’s solution is now standardtechnology in highenergy laser optics.
