Abstract

We propose and demonstrate a reconfigurable data exchange device for wavelength-division multiplexing (WDM) and mode-division multiplexing (MDM) compatible optical networks, which is capable of exchanging data information between a fundamental mode (TE₀) signal and an arbitrary high-order mode (TE_x) signal with the same wavelength. We experimentally demonstrate exchange for a TE₀ mode signal and a TE₁ mode signal. The insertion loss is about 7.5 dB including terminal coupling loss, the extinction ratio is more than 20 dB within the C band. The crosstalk for the TE₁-to- TE₀ and TE₀-to-TE₁ mode conversions is measured to be less than -22 dB and -16 dB, respectively. Clear and open eye diagrams of two different wavelength signals at 10 Gb/s are obtained. The proposed scheme is expected to be used for on-chip WDM-MDM compatible networks in future due to its scalability, compact size and reconfigurable functionality.
