Paper Abstract

A micro-machined MEMS variable optical attenuator capable of greater than 40 dB dynamic range is described. The device consists of an electromagnetically actuated gold-coated silicon micro-mirror rotating around a 100 µm-diameter shaft and a miniature driven coil. Enabling technology is precision EDM machining and laser cutting. The attenuator is scalable to a discrete array to implement a WDM drop module of an add/drop multiplexer and allows the realization of high capacity cross-connects.
