Considering the application requirement of micro-optical-electro-mechanical systems(MOEMS)chip in the medium and large caliber howitzer fuze,a MOEMS packaging method was proposed.The optical fiber po-sitioning structure was designed in the fiber groove to realize the passive alignment of the optical fiber.After the optical fiber alignment,the optical fiber was reliably fixed axially by using epoxy adhesive outside the chip.The finite element simulation analysis of the fiber positioning structure was carried out by ANSYS Workbench soft-ware,and the anti-high-overload capability of the optical path was tested by force hammer test and high speed centrifugal test.The results of simulation and test indicated that the packaged fiber optical path can achieve sta-ble transmission of light energy in both the service processing unexpected drop environment and the normal launch environment,which was of important significance to promote the application of MOEMS technology in the medium and large caliber howitzer fuze.
