摘要

Abstract

Handedness-selective chiral transport is an intriguing phenomenon that not only holds significant importance for fundamental research but also carries application prospects in fields such as optical communications and sensing. Currently

on-chip chiral transport devices are static

unable to modulate the output modes based on the input modes. This limits both device functionality reconfiguration and information transmission capacity. Here

we propose to use the incident polarization diversity to control the Hamiltonian evolution path

achieving polarization-dependent chiral transport. By mapping the evolution path of TE and TM polarizations onto elaborately engineered double-coupled waveguides

we experimentally demonstrate that different polarizations yield controllable modal outputs. This work combines Multiple-Input

Multiple-Output

and polarization diversity concepts with chiral transport and challenges the prevailing notion that the modal outputs are fixed to specific modes in chiral transport

thereby opening pathways for the development of on-chip reconfigurable and high-capacity handedness-selective devices.
