An acousto-optic modulator includes an acousto-optic bulk medium and transducer attached to the acousto-optic bulk medium. The transducer includes an electrode circuit and plurality of piezoelectric platelet segments attached to the bulk medium and supporting the electrode circuit. The piezoelectric platelet segments are configured for reducing shear stress and susceptibility to fracture due to temperature extremes.

L'invention concerne un modulateur acousto-optique qui comprend un support acousto-optique et un transducteur fixé audit support. Le transducteur comprend un circuit d'électrode et plusieurs segments de lamelle piézoélectriques fixés au support et supportant le circuit d'électrode. Les segments de lamelle piézoélectriques sont configurés de manière à réduire la contrainte de cisaillement et le risque de rupture dus à des températures extrêmes.
