摘要

为了提升垂直排列硅上液晶(VA-LCoS)器件的反射率，本文通过建立常黑型VA-LCoS的三维光学模型，分别用圆偏振光和线偏振光入射，研究了预倾角、液晶盒厚和入射光波长对VA-LCoS器件的反射率的影响。结果表明：使用圆偏振光入射能彻底消除亮态像素内黑色区域。本文条件下，1.6

m盒厚的VA-LCoS在圆偏振光入射时有最大的反射率。本研究的结论对VA-LCoS的设计和制备具有一定的指导意义。

Abstract

To improve the reflectivity of vertical alignment Liquid Crystal on Silicon (VA-LCoS)

we built a three-dimensional (3D) optical modeling for the normally black VA-LCoS mode

and investigated the effects of the gap of liquid crystal cell

the pretilt angle of liquid crystal and wavelength of incident light on reflection for linearly polarized light and circle polarized light as incident light

respectively. As a result

the black zone in the on-state pixel was eliminated by using circle polarized light as incident light. Moreover

the VA-LCoS has the highest reflection as the cell gap is 1.6

m. The results have an important guiding significance for the design and preparation of VA-LCoS.
