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.

Silicon photonics has become a commonly used paradigm for on-chip interconnects to meet the requirements of higher bandwidth in computationally intensive applications for manycore processors. Design of an optical switch is a vital aspect while constructing an optical NoC topology which influences the performance of network. We present a HoneyComb optimized reconfigurable optical switch (HCROS), a 6 × 6 non-blocking optical switch where optimized reconfiguration of optical links utilizing the states of basic 2 × 2 optical switching elements (OSE) was achieved while keeping the input-output (I/O) interconnection intact. The proposed 6-port HCROS architecture was further optimized to reduce the number of OSEs to minimize overall power consumption. We proposed a generic algorithm to find the optimal switching combination of OSEs for a particular I/O link to minimize the insertion loss and power consumption. In comparison to other non-blocking architectures, a maximum of 66% reduction in OSEs was observed for the optimized HCROS, which consumes only 12 OSEs. Simulations were performed for all 720 I/O links in different configurations to evaluate the power consumption and insertion loss. We observed up to 92% power savings in the case of optimized HCROS as compared to un-optimized HCROS, and a 79% minimization in insertion loss was also reported as a result of optimization.
