Polarization-diversity 4× 4 Si-wire optical switch
2015 International Conference on Photonics in Switching (PS), 2015•ieeexplore.ieee.org
… Recently, we have reported a PR-free polarization-diversity 2 × 2 switch [7] and
intersection [8], which are basic components of the multi-port switch. In this report, to the
best of our Nnowledge, the first demonstration of a polarization-diversity strictly non-blocNing
4 × 4 Si-wire optical switch is presented. The switch is in the path-independent insertion
loss (PILOSS) topology [9] and in the PR-free configuration. …

We present a polarization-diversity 4 × 4 silicon-wire optical switch on a 2.1-mm × 1.1-mm die, which employs the TE and TM components but no polarization rotator for simple fabrication. The switch exhibited 12.5 dB on-chip loss, 1.9 dB PDL, and ~10 ps DGD.
