In this thesis , optical couplers consisting of multimode interference ( mm ! ) coupler , y branch , directional coupler ( dc ) and mach zehnder interferometer ( mzi ) were analyzed and simulated 本論文對各種平面波導(dǎo)型耦合器: mmi 、分支波導(dǎo)、定向耦合器和mach - zehnder進(jìn)行了模擬和優(yōu)化設(shè)計。
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 在輸入耦合器方面,借助于波導(dǎo)耦合和外腔式波導(dǎo)激光器的相關(guān)理論,設(shè)計了工藝上可行的錐型耦合器,確定了透鏡、耦合器的尺寸以及耦合器與透鏡的相對位置:耦合透鏡的焦距為65mm ,直徑為srnm ,耦合器的長度為15mm ,輸入端直徑為17mm ,輸出端直徑為0
