Anderson localization

We have numerically studied the Anderson localization (AL) in 3D disordered systems, where its experimental demonstration is particularly tricky because of the restrictive Ioffe-Regel criterion. We employ an ab initio approach by using a finite difference time domain (FDTD) code in order to simulate a time-of-flight experiment to demonstrate the optical AL in micron-sized samples.

We also used the FDTD code to investigate the effect of disorder on the optomechanical forces. The recent establishment of even more sophisticated technologies for the fabrication of nano-structured objects and beam shaping, optical manipulation has seen an increasing interest in the possibility to handle even more complex object.
