Peter T. Rakich

Interests: 

The Rakich group focuses on experimental nonlinear optics and spectroscopy. Research areas include: the study of natural and artificial forms of optical nonlinearity in nanostructured effective media; the dynamics and evolution of nonlinear systems at new time and length scales; optical forces and energetics in nanoscale systems; nonlinear nano-optomechanical interactions.
