摘要:

利用飞秒激光直写技术制备了由深浅交替波导组成的超晶格,在实验上观察到了二维孤子。我们发现,线性衍射图案的对称性,以及孤子的形状和阈值功率有很大的不同,为深和浅的网站为中心的激发。因此,体孤子和表面孤子集中在深波导需要低得多的功率比浅网站上的同行。

英文摘要:

We observe experimentally two-dimensional solitons in superlattices comprising alternating deep and shallow waveguides fabricated via the femtosecond laser direct writing technique. We find that the symmetry of linear diffraction patterns as well as soliton shapes and threshold powers largely differ for excitations centered on deep and shallow sites. Thus, bulk and surface solitons centered on deep waveguides require much lower powers than their counterparts on shallow sites.
