Abstract

The alignment of single mode optical fibres using thermally actuated cantilever platforms is investigated. These devices F depend on their operation on differential thermal expansion of materials. An analysis and modeling of these thermal microactuators for fibre alignment purposes is discussed. The simulation results of microactuator deflection and the 4 coupling losses of single mode fibres by using the designed Pi-Shape microactuator are presented. By setting the length of the beam to 3mm and the length of the deflecting cantilever section to 2mm, the fibre-to-fibre coupling loss is only 0.315 dB.
