摘要
本文利用MSLM电光调制理论对几种实用电光晶体的综合电光性能进行了理论分析和比较。讨论了材料固有的铁电相变及自然双折射等特性与器件制作工艺的兼容性问题。结果指出LiNbO_3、LiTaO_3、BSO是目前可以利用的三种各具特点的电光晶体。
The electro-optic modulation sensitivity and spatial resolution are theoretically studied for MSLM with oblique-cut E-O crystals such as KNbO3, BaTiO3, LiNbO3, LiTaO3 and BSO. It is evident that the E-O modulation transfer is determined by both dielectric and electro-optic properties of crystals which vary with the crystal orientation. Although KN and BT offer higher sensitivity and better spatial resolution, the fabrication processes set a limit to them in MSLM with low ferroelectricity phase transition characteristics. The Influences of natural birefringence of selecting electro-optic materials for fabricating advanced MSLM has been established.
