【摘要】 为了使光学系统更加紧凑化和稳定化,本文提出了一种单晶集成的1×N电光开关:它有2个折射面,4个互相垂直的全内反射面,和N-1个电光调制器。还得到了该种1×N电光开关的构成条件:发生两相邻反射的反射面必须互相垂直。并对晶体的结构进行了优化,通过调整光束输出面与光轴的夹角来改变光束出射角,使得接收端易于接收输出的光信号。给出1×3电光开关的实例。更多还原

【Abstract】 For compactness and stability of optical system,electro-optic 1×N switch integrated in a single slab of LiNbO3 was proposed,which was composed of 2 refractive interfaces for beam input and output,4 reflective interfaces for total-internal reflection,and N-1 E-O modulators with pairs of electrodes.Then the requirements for this new type of 1×N switch were obtained that the interface for(k+1) th reflection must be perpendicular to the interface for k th reflection.And by choosing the angle between the normal of output face and the optic axis appropriately,a good arrangement with output positions for receiving output signals can be achieved.A practical example 1×3 switch is given.更多还原
