Abstract
The switching and routing is essential for an advanced and reconfigurable optical network, and great efforts have been done for traditional single-mode system. We propose and demonstrate an on-chip switch compatible with mode-division multiplexing system. By controlling the induced phase difference, the functionalities of dynamically routing data channels can be achieved. The proposed switch is experimentally demonstrated with low insertion loss of ~1 dB and high extinction ratio of ~20 dB over the C-band for OFF-ON switchover. For further demonstration, the non-return-to-zero on-off keying signals at 10 Gb/s carried on the two spatial modes are successfully processed. Open and clear eye diagrams can be observed and the bit error rate measurements indicate a good data routing performance.
Highlights
To satisfy the rapidly increasing demands on high-speed data transfer for cloud computing and data-intensive applications, silicon photonic interconnects have attracted wide attentions as a promising candidate for the next-generation platform alleviating the communication bottleneck and unfavorable power scaling [1,2,3]
