We demonstrate spatial solitons via twin-beam second-harmonic generation in hexagonal lattices realized by poling lithium niobate planar waveguides. These simultons can be steered by acting on power, direction, and wavelength of the fundamental frequency input.
我们通过在极化铌酸锂平面波导实现的六角形晶格中利用双光束二次谐波产生来演示空间孤子。这些孤子可以通过作用于基频输入的功率、方向和波长来进行操控。
