【摘要】 本文主要研究外加电场极化法制备周期极化铌酸锂晶体(PPLN)的技术和应用，并利用周期极化铌酸锂晶体具有的特殊化学性质，提出在局部畴反转的铌酸锂衬底上刻制出V型槽的方法，这种V型槽将用于简化铌酸锂光电器件的耦合封装。 本文简要介绍了周期极化铌酸锂的发展历程和应用前景。其次，分析比较了周期极化技术的几种工艺过程，着重研究了外加电场法，之后，进行可计数的高压脉冲电源的设计与实验，完成了铌酸锂晶体的光刻和液体电极的制作，为实现周期极化铌酸锂打下了坚实的基础，进行实验，分析结果。最后，提出改进方案。更多还原

【Abstract】 A technique for periodically poled lithium niobate by spatially selective electric field and its applications is studied.V grooves fabricated in LiNbO3 substrates via its the special characteristics is suggested. The grooves will simplify the attachment and package of optoelectronic applications.The history and prospect of periodically poled lithium niobate technique is briefly introduced. Secondly presenting and contrasting the methods of the technique,mainly electric field poling method is studied. Next detailed design and experiment on the high voltage pulse source which can take count is described.Then the LiNbO3 samples is utilized conventiomal photolithographic patterning steps. Liquid electrodes are designed .It has made a powerful basis for PPLN . After experiments, the result is analyzed. The last part is the improvement.更多还原
