2.5-dB loss, 100-nm Operating Bandwidth, and Low Power Consumption Strictly-Non-Blocking 8 × 8 Si Switch

We present a design- and process-optimized 8×8 silicon photonic switch exhibiting an ultralow on-chip loss, an ultra-wide -30-dB crosstalk bandwidth and low power consumption. A fully-integrated polarization-diversity 8×8 switch is also fabricated and characterized to promise its practical uses.
