提出了磁通环上双势阱隧穿的拓扑（Aharonov-Bohm）抑制的经典波动光学模拟。该光学系统由一个均匀扭曲的光纤与结构化的环形芯，其中的纤维扭曲模仿的磁通量在相应的量子力学问题的作用。陷在光纤的环形芯中的光波经历额外的拓扑（Aharonov-Bohm）相位，这可能导致在扭转率的某些值处的光学隧穿的破坏。
A classical wave-optics analog of topological (Aharonov-Bohm) suppression of tunneling in a double-well potential on a ring threaded by a magnetic flux is proposed. The optical system consists of a uniformly twisted optical fiber with a structured annular core, in which the fiber twist mimics the role of the magnetic flux in the corresponding quantum-mechanical problem. Light waves trapped in the annular core of the fiber experience an additional topological (Aharonov-Bohm) phase, which may lead to the destruction of optical tunneling at certain values of the twist rate.
