用光线追迹迭代法和解析法设计无球差非球面波导短程透镜的母线
用单点金刚石超精加工和凹面波导制备工艺
研制成孔径和有效孔径分别为8和6mm的LiNbO

导短程透镜.实验表明
器件在有效孔径内无球差;对4mm宽的输入平面波光束
焦点衍射光斑半宽度为4μm;透镜插入损耗为~1dB.
Both the ray tracing algorithm and the general solution of geodesic lens were used to design the meridional curves of spherical-aberration-free aspherical lens.The single point diamond machining and a technology for fabricating depression waveguide were used to fabricate the geo- desic lenses in LiNbO

. The lens aperture and effective aperture are 8 and 6mm
respectively. The experiments show that the lens is spherical-aberration-free in the range of 6mm effective aperture
the diffractive spot size is 4μm for input beam of 4mm width and the lens insertion loss is about 1dB.
