            Abstract : 
In this work, we study the effect of the shutter thickness on the optical attenuation in an optomechanical variable optical attenuator. Both experimental and simulation results show a maximum in the received optical field with the shutter displacement, which increases at large shutter thickness. This behaviour has not been reported or analysed before
