We demonstrate a low-crosstalk 2 × 2 thermo-optic switch with silicon wire waveguides. The device is based on a 2 × 2 array of Mach–Zehnder interferometer (MZI) switches. Lowest crosstalk levels of –50 dB and –30 dB are obtained for ‘bar’ and ‘cross’ switching states, respectively. An intersection in the switch is important for low-crosstalk operation. The power consumption of one MZI element switch is 40 mW and the total power consumption of the device is at most 160 mW.
