3 × 3 Non-Blocking SOI Electro-Optic Switch

Optical switch is a promising technology for high bandwidth communication in data centers. In this letter, we demonstrate a
$3\times 3$
switch with p-i-n phase shifters. With pull-push configuration, the average on-chip insertion losses at 1550 nm of
$3\times 3$
switch are 3.38 ± 0.7 dB and 4.04 ± 1.42 dB for “all-cross” and “all-bar” states, respectively. The optical crosstalk is lower than −10.57 dB from 1530 to 1565 nm for the worst case. The measured rise/fall time of the switch upon electrical tuning is 2.4(8.0) ns.
