南京邮电大学硕士学位论文 Abstract Abstract With therequirement work bandwidth continually increasing,this results in DWDM technology rapid development,as an example of all optical fiber can transmit several hundreds tothousandwavelengths,and each wavelength can carry more than 0Gbit/ technology are now being challenged by such huge-capacity ·E-0 method totransmitthesignal could hardly satisfy SOhighcapacityswitching switching device isbeing abottle-neck to switch based 011Micro-optical—electro—mechanical Systems (MOEMS)technology hasbeenbelieved that itisthefirst choice as anode offuture work、Ⅳim order toachieve high speed informationexchange,optical switch should have fastswitch orderto achieve large-scale andhuge—capacity opticalswitch,it should have low insertion order to achieve long life-span,it should have highly mechanical stability and overall ,optical switch based onMOEMS isbeen regarded as themostprosperous scheme infuture. nis dissertation discusses and makes athorough research on theopticalswitch based Oil 3DMOEMS paper emphasizes thedesignandanalyzes theoptical switch based on 3DMOEMS;design the structure oftheoptical as the inputand output fiber plane,MOEMS mirrors,roof-,we setup one—dimensional virtualdescription of beam propagation model,analyze anddesign theMOEMS mirror’Sparameters,then,we analyze and discuss about micro-ddven system,and itscontrol theend we design novel switch housing,pare谢th typically aresult,the opticalswitchCan minimize thermalexpansion andmechanical shock,SO it has pact,small tilt angle,easy assemble optical switchCan satisfy thedemands ofthe hi曲speed works。 Then we discusstheapplications of theoptical aswecan use optical switch make up ofOXC,OADM,all work,etc. Key words:all—work(AON
