全息明孤子的波导特性

Waveguide induced by bright holographic solitons

研究了光折变晶体中的全息明孤子所产生的波导的特性,结果表明波导所有可能的导模数依赖于产生波导的全息明孤子光的强度.利用数值计算给出了在不同的孤子强度时波导的导模并考察了波导对导模和正弦余弦波的动态导引.

The properties of waveguides induced by one-dimensional steady-state bright holographic solitons in photorefractive medium are studied numerically. The results show that the number of possible guided modes in such a waveguide depends on the peak intensity of the soliton. The dynamical evolutions of the guided modes of the waveguide are presented. And the wave guiding in such a waveguide is also considered for a probe beam with cosine dependence or sine dependence.
