我们提出了一种操纵方法来改变暗孤子与探测波相互作用产生的光学视界下暗孤子的波速和灰度度。据我们所知，光学视界效应首次被证明能够诱导黑孤子和灰孤子之间的可逆转换。这种可逆的孤子变换和控制过程源于探测诱导的非线性相移和暗孤子的内位相之间的内在竞争。在由两个光学事件视界组成的级联系统中，我们还观察到了新的光学孤子隧穿现象，其中暗孤子可以有目的地进行纵向重置。结果可能在信息伪装中得到应用，例如对接收器有效地隐藏中间光纤部分的存在。
We propose a manipulation approach to vary the wave speed, as well as the grayness, of dark solitons under the optical event horizon arising from the interaction between a dark soliton and a probe wave. To the best of our knowledge, the optical event horizon effect is demonstrated for the first time to be capable of inducing a reversible conversion between a black soliton and a gray one. This reversible soliton transformation and control process originates from the intrinsic competition between the probe-induced nonlinear phase shift and the internal phase of the dark soliton. In a cascaded system consisting of two optical event horizons, we also observe the new optical soliton tunneling phenomena where a dark soliton can be reset longitudinally purposely. The results may find applications in information cloaking such as effectively hiding the presence of intermediate fiber section to the receiver.
