We demonstrate thermo-optic control on the propagation of optical spatial solitons in nematic liquid crystals. By varying the sample temperature, both linear and nonlinear optical properties of the reorientational material are modulated by acting on the refractive indices, the birefringence, and the elastic response. As a result, both the trajectory and transverse confinement of spatial solitons can be adjusted, demonstrating an effective means to tune and readdress self-induced optical waveguides.
我们证明了向列相液晶中光空间孤子传播的热光控制。通过改变样品温度，可以通过作用于折射率、双折射和弹性响应来调制各向异性材料的线性和非线性光学性质。结果，空间孤子的轨迹和横向限制都可以进行调整，这证明了一种有效调节和重新定位自诱导光导的方法。
