Michal Lipson

Michal Lipson (born 1970) is an American physicist known for her work on silicon photonics. A member of the National Academy of Sciences since 2019, Lipson was named a 2010 MacArthur Fellow for contributions to silicon photonics especially towards enabling GHz silicon active devices . Until 2014, she was the Given Foundation Professor of Engineering at Cornell University in the school of electrical and computer engineering and a member of the Kavli Institute for Nanoscience at Cornell. She is now the Eugene Higgins Professor of Electrical Engineering at Columbia University. In 2009 she co-founded the company PicoLuz, which develops and commercializes silicon nanophotonics technologies. In 2019, she co-founded Voyant Photonics, which develops next generation lidar technology based on silicon photonics. In 2020 Lipson was elected the 2021 vice president of Optica (formerly the Optical Society), and serves as the Optica president in 2023.

Education

After spending two years as a BS student at the Instituto de Física of the University of São Paulo, Lipson obtained a BS in physics from the Technion – Israel Institute of Technology in 1992. She went on to obtain a PhD in physics from the same university in 1998, with the thesis topic "Coupled Exciton-Photon Modes in Semiconductor Optical Microcavities." Lipson spent 2 years as a postdoctoral associate with Lionel Kimerling at MIT, and then accepted a position at Cornell University in 2001.

Career and research

Lipson is best known for her work on silicon photonics. She developed (along with other researchers around the world at IBM, Intel, Ghent University) silicon photonic components such as waveguide couplers, ring resonators, modulators, detectors, WDM wavelength sources and sensors on silicon platform. She published the first paper on a class of versatile waveguides known as Slot-waveguides in 2004, which has since been cited over one thousand times. In all her work has been cited 32,373 times (as of January 18, 2018). She was also the first to demonstrate optical parametric gain in silicon, which was considered an important step towards building optical amplifiers in silicon.

Lipson's McArthur fellowship citation mentions her work in ring modulators (circular waveguides) as the key contribution of Lipson via the continued refinement of both opto-electronic and purely optical circuits for smaller size,
. increased efficiency, and accelerated switching speed
. The resulting silicon-based photonic integrated circuits have the potential to improve signal transmission and processing dramatically.

Lipson has received numerous honors, including being the recipient of a Fulbright Fellowship and an National Science Foundation CAREER Award. She is also an elected fellow of Optica. Her current research interests include optical metamaterials, low-power and compact optical modulators, and slot waveguides. Her work has appeared in ''Nature'', ''Nature Photonics'', and other journals.
