The PZT actuators deploy 3.1-μm PZT layer. The developed PZT-driven microelectromechanical systems VOA comprising a large Si reflection mirror integrated with a dual core fiber collimator in 3-D light attenuation arrangement. The curve of the attenuation versus driving voltage shows rather uniform changing rate taking the advantage of the linear relation between the optical angle and the driving voltage. Dynamic range of 40-50 dB is achieved at 1 and 1.2 dc driving voltages, respectively. © 2009 IEEE.||Source Title:||IEEE Journal on Selected Topics in Quantum Electronics||URI:||http://scholarbank.nus.edu.sg/handle/10635/68706||ISSN:||1077260X||DOI:||10.1109/JSTQE.2009.2022959|
