Concurrent data and power transmission using mode division multiplexing over a two-mode fiber

This is the authors' abstract. We don't add key points for this paper.

Next-generation mode division multiplexing (MDM) systems aim to integrate concurrent functionalities within a single optical fiber efficiently. In this work, we report on harnessing MDM to simultaneously provide data transmission and power delivery over a two-mode fiber (TMF). We deployed a 1-km TMF to convey a 1 Gbps on-off keying (OOK) data signal and deliver a 17.12 mW input optical power. Through switching the mode allocation (LP₀₁/LP₁₁ for data/power), we examined the suitability of both integrated communication and PWoF functionalities. During our analysis, we established a robust communication link with 1.933×10⁻⁵ bit error rate (BER) using the LP₁₁ mode for communication while simultaneously achieving electrical power delivery of ∼2.75 mW at the receiver side using the LP₁₀ mode. This successful integration proves the feasibility of harnessing the TMF for simultaneous data and power transmission in next-generation integrated systems/networks encompassing communication and power.
