Electromagnetic variable optical attenuator

Abstract

Electromagnetically actuated micromirror is a promising candidate for optical switching applications. In this research, we have designed, fabricated and tested a microelectromechanical systems (MEMS) variable optical attenuator (VOA) composed of an electromagnetic micromirror and integrated fibers. The effects of fiber arrangement and the deployment of lensed fibers on the attenuator performance are analyzed based on experimental results.
