Abstract
We propose and experimentally demonstrate an on-chip switchable mode exchange utilizing a Mach–Zehnder interferometer assisted by a phase shifter. The switchable functionality, which is essential for an advanced and reconfigurable optical network, can be realized by controlling the induced phase difference. The measured extinction ratio is over the band for OFF–ON switchover. For demonstration, open and clear-eye diagrams can be observed when processing non-return-to-zero on–off keying signals at 10 Gb/s. The bit error rate measurements indicate a reasonable power penalty of less than 1 dB for two-mode exchange. The proposed device can further promote advanced and flexible mode-multiplexing optical networks.
