Compact silicon on insulator based 2 \times 2 Mach–Zehnder interferometer electr

We report a compact 2 × 2 Mach–Zehnder interferometer (MZI) electro-optic switch fabricated on a siliconon-insulator using standard complementary metal-oxide semiconductor (CMOS) processes. With a short modulation arm length of 200 \mu m, the crosstalk is reduced to -22 dB by the new modulation sche
