Nanophotonics

Prof. Albert Polman

Center for NanophotonicsFOM-Institute AMOLF, Amsterdam

Debye Institute, Utrecht University

Nanophotonics: defined by its applications • communications technology• lasers• solid-state lighting• data storage• lithography• (bio-)sensors• optical computers• solar cells• displays• medical imaging• light-activated medical therapies

Nanophotonics is a unique part of physics/chemistry/materials science because it combines

a wealth of scientific challenges with a large variety of near-term applications.

Large interest from industry infundamental research on nanophotonics
