Abstract :
Low-crosstalk electrically-driven 2 × 2 InGaAsP photonic-wire Mach-Zehnder interferometer optical switches are demonstrated on the III-V CMOS photonics platform. The low carrier-induced loss in InGaAsP enables crosstalk as low as -30 dB. The error-free switching of 12.5 Gb/s optical signals is also achieved with power penalty of less than 2 dB.
