I am an Iranian graduate student in the group of "Photon Scattering" at AMOLF, working under supervision of Ad Lagendijk.

My research topic is about observation of Anderson localization of light in strongly-scattering media. I am also interested in Anisotropic diffusion of light and optical non-linearity in scattering media.

2009-01-18: Diffusion theory describes the distribution of second harmonic light, which is generated inside multiple-scattering media, but fails in prediction of the conversion rate.
Multiple scattering can enhance, by several orders of magnitude, the optical nonlinear conversion rate in a peice of semiconductor. Using effusion microscopy We have recorded, for the first time, how second harmonic light is distributed inside a highly scattering slab of porous-GaP. We have shown that this distribution is very much close to the prediction of the diffusion theory. However, the efficiency of the conversion process cannot be described by the available theories. Despite the very promissing applications and recent experimental advances, a general theory for describing nonlinear optical processes in strongly scattering media is still missing.
