Here we introduce a novel technique for characterizing the deflection and force sensitivity of a silica micro-cantilever transducer, with inherently defined planar Bragg gratings. The technique uses a 3D scanning surface profiler to deform the micro-cantilever both vertically and horizontally whilst simultaneously monitoring a set of multiplexed Bragg gratings. By using this characterization technique a theoretical model for the cantilever's optical response is tested.
