In this article, an optical fiber switch based on a digital actuator is presented. Four discrete positions are obtained through a magnetic holding of a Mobile Permanent Magnet (MPM) placed in a fixed square cavity. The MPM can switch, thanks to Lorentz's force, between the four corners of the cavity. A 1X4 optical fiber switch is obtained by fixing a prismatic mirror on the top side of the MPM and an N × N switch array can be obtained using a matrix of this unit. After a presentation of the actuator principle, the optical switch is detailed and characterized for telecommunication purpose.

基于数字执行器的1X4光开关

在本文中，提出了一种基于数字致动器的光纤开关。通过放置在固定方腔中的移动式永磁体（MPM）的磁性保持，可以获得四个离散位置。由于洛伦兹的作用，MPM可以在型腔的四个角之间切换。通过在MPM的顶部固定一个棱镜可以得到1X4光纤开关，并且可以使用此单元的矩阵获得N×N开关阵列。在介绍了执行器原理之后，将详细介绍光开关并对其进行表征，以用于电信目的。
