| 摘 要： | 从理论上研究了由一维稳态屏蔽光伏孤子诱导的非线性波导,结果表明在加偏压的光伏光折变晶体中,例如铌酸锂,无论是明孤子还是暗孤子都能诱导出非线性波导.推导出了在一般条件和低振幅条件下探测光束满足的波方程.

| Abstract: | We study theoretically the properties of nonlinear waveguides induced by one-dimensional steady-state screening-photovoltaic spatial solitons. It shows that the waveguides can be induced by both bright and dark spatial solitons in the biased photovoltaic-photorefractive crystal such as LiNbO3. We also derive wave equations for the probe beam in the general condition and low-amplitude condition. |
