Abstract: Special device modeling, design and layout, and precision processing controls were employed to fabricated new balanced-bridge 2 $MUL 2 and 4 $MUL 4 switches on X-cut, Y-propagation LiNbO$-2$/ substrate using Ti indiffused optical waveguides. The best of these devices achieved extinction ratio and crosstalk isolation of better than 93 dB electrically (46.5 dB optically). The new switches demonstrate good reproducibility with electrical crosstalk less than $MIN@80 dB.!11
