摘　　要：利用衍射光场辐照高浓度LiNbO3:Fe晶体,通过光折变效应在晶体中写入平面波导。研究了各种实验参数对写入波导特性的影响并测量了平面光波导的横向折射率和周期。实验结果证明,使用辐照法在LiNbO3:Fe晶体中写入平面波导是简便可行的,并且具有允许低功率写入、存储时间较长,光折变灵敏度高的特点。High doping LiNbO3：Fe crystal write-in slab waveguide by photorefractive effect by diffraction field was rescarched.The waveguide oharaoters mfluenoed by experimental oonditioa was studied and the transverse refractive and perriod of stab waveguide was measured.It is approved that LiNbO3：Fe crystal has the feature of low power write-in,long storage time and high sensitivity. It is feasible that the irradiation method is convenient to slab waveguide storage in LiNbO3：Fe orystal.
