We address light propagation in Vogel optical lattices and show that such lattices support a variety of stable soliton solutions in both self-focusing and self-defocusing media, whose propagation constants belong to domains resembling gaps in the spectrum of a truly periodic lattice. The azimuthally rich structure of Vogel lattices allows generation of spiraling soliton motion.
我们研究了 Vogel 光学格子中的光传播,并表明在自聚焦和自散焦介质中,这种格子支持多种稳定的孤子解,其传播常数属于类似于真实周期性格子谱隙的区域。Vogel 格子丰富的角向结构允许产生螺旋孤子运动。
