Colloquium

The OSC Colloquium series is a dynamic forum for the interchange of ideas, techniques and research in all areas of optics, wherein academic scholars and industry leaders lead discussions about groundbreaking research and open the floor to questions and comments. Students, faculty members, members of the optics community and the public are all invited to attend.

Colloquium is held on Thursday in Meinel 307 each week during the academic year.

    Speaker: Marin Soljacic Topic: New physics from photonic systems Visit our website for future lecture dates and speaker information: http://www.optics.arizona.edu/news-events/events/colloquium For a list of our archived lectures: http://www.optics.arizona.edu/news-events/events/colloquium/archive

    Nanophotonics offers unprecedented opportunities to mold the flow of light: novel material-systems can thus be implemented in which laws of physics can be tailored almost at will. I will describe this on a few recent examples from our work: non-Abelian topology, new framework for understanding...

    nothing was really there? Hardly! The camera pixels measure “raw” light intensity where the
    encoded information often is much richer than a human observer could tell...
