The optimization of switching characteristics is performed for switching voltage and device size. This structure has a total length of 5.5mm and a width of 20.6um. For the first time, the driving voltage as low as 1V has been achieved with acceptable crosstalk levels (in the range of -22dB to -28dB) for communication applications. Using a beam propagation method (BPM), we demonstrate that the switch is polarization independent and suitable for low attenuation optical window (1300nm and 1550nm) operation as well.  <br /><br />Full text: <a class="file" href="/PLP/index.php/letters/article/view/3-14/151" target="_parent">PDF</a> <br /><br /> <strong>References:</strong> <ol> <li>R.
