摘要：

Two microphotonic switches have been proposed and fabricated in a silicon-based silicongermanium material system by using silicon optical bench technology. The switches are configured for a 3 x 2 symmetrical structure of three input waveguides, a central section, and two output waveguides. The operating wavelengths of the switches are specially designed in C-band, i.e. 1530 to 1570 nm. The measured average crosstalk is about - 20 dB, and total insertion loss is about 5 dB.
