An array of permalloy core solenoids is micromachined as microactuators on (100) silicon wafer. Then anisotropic etching of silicon in KOH solution forms the U-grooves beside the microactuators. The micromachining difficulties from the coexistence of 3-D MEMS devices and deep grooves on chip are overcome successfully. Then two fibers and permalloy piece are assembled onto the wafer together with the microstructures finishing the prototype of the new type MEMS VOA. Third, the inductance, resistance and Q value of the microfabricated solenoids are measured in the frequency range of 1-40 MHz.

第二，新开发了使用SU-85的正胶、负胶复合微加工工艺，在（100）硅片上加工了新型可变光衰减器的铁芯MEMS螺线管型电磁微执行器阵列；用KOH水溶液对（100）硅片进行湿法刻蚀，在电磁微执行器旁边微加工了V形槽结构组合，开发了单片集成三维MEMS器件和深槽的微加工关键技术；然后经过微装配制作出了电磁驱动的光纤偏移型MEMS可变光衰减器的样机。

Then the MEMS solenoid type electromagnetic actuating and novel, frictionless and wear-free, and simple structure are designed for fiber-deflecting type MEMS VOA: One of the two coupled single mode fibers is completely fastened in one of the three aligned U-shaped grooves while the deflectable fiber is partially fixed in another groove with a long front section suspending over the wider groove as a cantilever beam. The two fibers, any one for input and the other for output, are well aligned initially so that the insertion loss is very low. Beside the deflectable fiber is a solenoid microactuator with a U-shaped permalloy core attracting a permalloy piece glued on side of the fiber cantilever so that the fiber is deflected and the optical power coupled between the fibers decreased continuously. Using MEMS solenoid as a continuous actuator and the novel structure of VOA are not seen in literature.

为光纤偏移型MEMS可变光衰减器设计了MEMS螺线管电磁驱动方式以及新颖的避免了静摩擦、磨损而且简单的整体结构形式：在硅基片的三段V形槽结构中，将两个对接单模光纤之一完全固定在基片上，只将另一根光纤的稍后部位固定于基片上而使其前端的一定长度悬空，形成一个悬臂梁结构；初始对准后两根光纤之间的光传输损耗很小；通过U型铁芯MEMS螺线管吸引固定于光纤悬臂梁上的坡莫合金片，驱动光纤悬臂梁连续偏移以使两根光纤之间功率传输系数连续变化，从而达到光功率连续衰减的目的。

According to the plane cross section assumption, configuration of a rod is expressed as a history of the cross section with arc coordinate. A special solution which stands for equilibrium in straight line state is obtained from differential equilibrium equation. Linear perturbation equation is derived and its general solution is obtained in which the integral constants are determined by constrained conditions at two ends of the rod. The condition of existence of non zero solution of the integral constants gives to the Greenhill formula of exact elastic rod model, which shows that the boundary of stable area is a closed curve and of symmetry, and inference of shearable and extensible to stability of the rod is depend on three factors: difference between flexibility of shear and extension of a section of the rod, bending stiffness and the length of the rod.
