We have fabricated optical channels in selectively masked planar GaAs/AlGaAs waveguide structures using both 10 MeV oxygen and 8 MeV carbon ions. Implantation at different temperatures appears to have a direct effect on the extracted propagation mode

We present the results of characterization of linear absorption and nonlinear refractive index of Au and Ag nanoclusters made by MeV ion implantation into LiNbO3. Ag was implanted at 1.5 MeV to fluences of 2 to 17 × 1016/cm2 at room temperature. Au

Single crystals of pure and Fe 3+ doped bismuth silicon oxide (Bi 12 SiO 20 ) have been grown by the Czochralski method. Bi 12 SiO 20 crystals grown over a wide range of conditions show an obvious tendency towards faceting. The faceting morphologies

An improved, explosively actuated closing switch has been developed for the Pegasus II capacitor bank. The new switch design uses an annular metal jet as the switch contact. It has lower resistance and inductance at early time than the original desig
