(2+1)-dimensional photonic crystals from Langmuir-Blodgett colloidal multilayers
Romanov, Sergei G.; Bardosova, Maria; Pemble, Martyn E.; Torres, C. M. Sotomayor
Angle-resolved transmission spectra of multilayers of two-dimensional colloidal crystals prepared by the Langmuir-Blodgett technique have been studied. In contrast to the light diffraction in three-dimensional colloidal crystals, optical spectra revealed only very weak correlation between layers in the Langmuir-Blodgett multilayers. Two reasons for the observed transmission minima have been identified: the diffraction at a stack of layers and the scattering of the incident beam by guided modes of the two-dimensional colloidal crystals.
