Optics and Quantum Electronics Group
Prof. Erich P. Ippen and Prof. Franz X. Kaertner

The RLE Optics and Quantum Electronics group pursues fundamental investigations of ultra-scale optical and quantum phenomena to advance the technologies of lasers, large-scale photonic integration, all-optical networks, photonic bandgap devices, frequency metrology, optical communications, nanoelectronic devices, biomedical optical imaging, and quantum computing. Work includes the development of solid state lasers and femtosecond pulse generation techniques which can achieve extremely high time resolutions on the femtosecond time scale, novel double-chirped mirrors, optical fiber lasers that can produce either high power femtosecond pulses, as well as short cavity fiber lasers, semiconductor saturable absorber mirrors, photonic bandgap resonators, and semiconductor quantum dots .


First demonstration of attosecond jitter ultrafast optical pulse trains from modelocked lasers

A research team from MIT Campus, MIT Lincoln Laboratory and Northern Illinois University led by Franz X. Kärtner receives a multiyear DARPA grant to explore compact, laser driven, coherent X-ray sources

Franz X. Kärtner joins the Center for Free-Electron Laser Science at DESY Hamburg and heads the Ultrafast Optics and X-rays Division. He also joined the Department of Physics at University of Hamburg, while continuing as Adjunct Professor in EECS at MIT
