FLUSHING, NY, October 30 2009 ― Physicists at Queens College have recently demonstrated the existence of a new type of light-matter quasi-particle that can arise when light hits specially designed photonic crystals. (Photonic crystals are structures with periodically modulated optical properties.)
A paper on their discovery appears in the November issue of Nature Photonics, currently the highest ranked journal in the fields of optics and applied physics.
This work was done collaboratively by the theory groups of Professors Lev Deych and Alexander Lisyansky, chair of physics, and the experimental group of ProfessorVinod Menon, all at Queens College. The structures studied were grown by a group headed by Professor Serge Oktyabrsky of the University at Albany, SUNY.
David Goldberg, the first author on this paper, is a PhD student in Prof. Menon's group.
"With further development, these quasi-particles can be used to slow down light and to study collective phenomena at the macroscopic scale," notes Menon.
