… Abstract: We demonstrate that record-high extinction-ratio of 50 dB is achievable in a 2×2
Si optical switch by making use of a variable splitter. The proposed switch will enable such
high extinction-ratio even in volume production using standard CMOS fabrication facilities. …
For this purpose, we propose a new design of the 2×2 optical switch. The primary structure
is the same as the conventional …
