waveguide coupling meaning in English

波导管耦合

As far as input coupling devices concerned , we design a feasible taper coupler by means of the theory of waveguide coupling and outside cavity waveguide laser and make decision of the sizes of the lens and the taper coupler , and the relative distance of them . the focus of the lens is 65mm and the radius is 5mm . the length of the taper coupler is 15mm , and the radiuses of the input and output ends separately are 17mm and 0 . 65mm
在输入耦合器方面，借助于波导耦合和外腔式波导激光器的相关理论，设计了工艺上可行的锥型耦合器，确定了透镜、耦合器的尺寸以及耦合器与透镜的相对位置：耦合透镜的焦距为65mm ，直径为srnm ，耦合器的长度为15mm ，输入端直径为17mm ，输出端直径为0
