An electro-optic Fabry-Pérot through-plane-modulator based on a Langmuir-Blodgett film

Abstract An electrically controlled Fabry-Perot optical modulator is described. A modulating material fabricated from a Langmuir-Blodgett film was used as the spacer layer. A change in reflectivity of 3 × 10 −4 has been realised with a drive voltage of 8 V.
