Abstract: The ability to generate and manipulate photons with high efficiency and coherence is of critical importance for both fundamental quantum optics studies and practical device applications. However mainstream integrated photonic platforms such as those based on silicon and silicon nitride lack the preferred cubic χ(2) nonlinearity, which limits active photon control functionalities. In this talk, I will present integrated photonics based on aluminum nitride (AlN), whose wurtzite crystal structure gives rise to the strong second-order optical nonlinearity and piezoelectric effect. Together with its low optical and mechanical losses, the integrated AlN photonics can provide enhanced χ(2) photon-photon interactions to achieve high fidelity photon control, including on-chip parametric down-conversion, coherent light conversion, spectral-temporal shaping, and microwave-to-optical frequency conversions.



2018 Kavli Prize Laureates Announcements:

Live webcast and Program: http://www.kavliprize.org/

May 31st 8:30-10:00am EDT/2:30-4pm CEST

Keynote speaker: Honorable Shirley Ann Jackson Ph.D., President, Rensselear Polytechnic Institute

Watch the live webcast of the 2018 Kavli Prize laureate announcements by the Norwegian Academy of Science and Letters in Oslo, Norway, and live coverage of a special Prize program from the World Science Festival in New York City, including a special keynote address by the Honorable Shirley Ann Jackson Ph.D., President, Rensselaer Polytechnic Institute. 

The Kavli Prize recognizes scientists for pioneering advances in our understanding of existence at its biggest, smallest, and most complex scales. Presented every two years in the fields of astrophysics, nanoscience and neuroscience, each of three prizes consists of USD $1 million. Laureates are nominated by committees whose members are recommended by The Chinese Academy of Sciences, The French Academy of Sciences, The Max Planck Society (Germany), The National Academy of Sciences (US), The Royal Society (UK) and the Norwegian Academy of Science and Letters. From these nominations, The Norwegian Academy of Science and Letters selects the laureates.

First awarded in 2008, the Kavli Prizes have so far honored 47 scientists from 11 countries – France, Germany, Japan, Lithuania, The Netherlands, Norway, Russia, Sweden, Switzerland, the United Kingdom and the United States. Winners receive gold medals in Oslo, Norway, in a ceremony presided over by His Majesty King Harald. A banquet takes place at Oslo’s famed City Hall. The Kavli Prize is a partnership between the Norwegian Academy of Science and Letters, The Kavli Foundation (USA) and the Norwegian Ministry of Education and Research.
