Piezooptical materials doped by silver nanoparticles for telecommunications

We present a new technological approach of using the known piezooptical glasses for telecommunications by introduction of the silver nanoparticles. The main principle consists of existence of the surface plasmon resonances of the silver nanoparticles in the spectral range 480 nm - 530 nm. The latter one favors an increase of their elastooptical properties closely connected with the acoustooptical efficiencies. Principal parameters of the silver nanoparticles, e.g. their concentration, nanoparticle sizes and type of the glasses is discussed.
