We demonstrate a new material composed of isotropic liquid crystal (ILC) blended with semiconductor nanoparticles,
which could result in a novel high-speed, multiple-notch broadband passive optical switch to selectively discriminate
bands of electromagnetic radiation in intelligence, surveillance, or reconnaissance systems. The new material has been
demonstrated high nonlinear 3rd order optical Kerr coefficients (light-induced refractive index change, n2) exceeding 100
times of classic nonlinear material CS2 with n2 = 1.2E-11 esu. Details of fabrication and experimental results are
presented.
