Multi-mode interference waveguides are fabricated inside silica glass by transverse writing geometry with femtosecond laser pulses. The influences of several wr
Using standard 0.18-μm CMOS process and the special platform for 8-inch phase change random access memory(PCRAM), the first Chinese 16k bits PCRAM chip has bee
We report an efficient pumping scheme which involves a direct excitation of the upper lasing level of a four-level laser in a Nd-doped Ca3(NbGa)2-xGa3O12 (Nd:CN
AlssNi5 Y8 Co2 and Al85Ni5 Y6 Co2Fe2 metallic glasses are fabricated by melt spinning. A kink or a small exothermic peak is observed for both the samples isothe
