Title: Compact 2X2 Optical Switch Using Silicon Photonics Technology for Optical Beam Forming Network
Abstract: We report the experimental demonstration of a 2×2 electro-optical switch in silicon-on-insulator. By controlling electro-optical phase shifter, light from any input waveguide can be directed to any output waveguide. Furthermore, the proposed optical switch can be expanded to be 1×N and N×N optical switch for optical beam forming network. The switch is fabricated by CMOS technology. In experiment, full 2×2 switching functionality is demonstrated at wavelength of 1.55 μm, with an average crosstalk of-14.6 dB and compact size of 300X100 um2.
