Abstract

The spectral switch phenomenon of light induced by scattering from a collection of particles is, to the best of our knowledge, reported for the first time. It is shown that when a spatially coherent light wave with a spectrum of Gaussian distribution is scattered from a collection of particles, the rapidly transition of the spectrum of the scattered field from red shift to blue shift (i.e., spectral switch) can be observed. It is also found that the spectrum of the scattered field will experience several spectral switches with the increase of the scattering angle.
