Silicon-photonics polarization-insensitive broadband strictly-non-blocking 8 × 8 blade switch

We present a 1-RU silicon photonics 8×8 switch with a low PDL (<;0.5 dB) and a broad operating bandwidth (35 nm at -20 dB crosstalk). 32-Gbaud DP-QPSK WDM transmission was demonstrated with no OSNR penalty.
