High performance mode (de)multiplexer assisted with a microring resonator on the lithium niobate-on-insulator platform. [PDF]

Nanophotonics
Abstract The high extinction ratio mode (de)multiplexer is a pivotal component in high capacity mode‐division multiplexing data communication and nascent on‐chip intermodal acousto‐optic modulators. Up to now, high performance on‐chip mode (de)multiplexers are still lacking for integrated AOMs on the lithium niobate‐on‐insulator platform. In this paper,
