A MEMS based in-plane fibre optic alignment device based on a scalable folded buckling mode electro-thermal microactuator has been developed. The bi-directional fibre alignment device, for use with standard single mode optical fibres, is formed from two opposed microactuators, and includes an etched channel with microsprings for fibre retention. The device is fabricated by deep reactive ion etching (DRIE) of bonded silicon-on-insulator. The optical/electrical/mechanical characteristics of the MEMS fibre aligner have been measured. The drive efficiency of the actuator peaks at around 6μm/Watt, whilst when configuring the device as a single mode fibre variable optical attenuator the fibre-to-fibre attenuation of the device is 24dB before failure.
