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。
The nonlinear waveguides induced by one-dimensional steady-state shielded photovoltaic solitons are theoretically studied. The results show that in the case of biased photovoltaic photorefractive crystals, such as lithium niobate, both bright and dark solitons can induce out-of- Linear waveguide. The wave equation of the probe beam under normal conditions and low amplitude is deduced.
