Observation of electro-optic and electroabsorption modulation in a Langmuir-Blodgett film Fabry-Perotétalon.
Electro-optic and electroabsorption modulation by use of a Langmuir-Blodgett (LB) film-based Fabry-Perot étalon is reported. The modulation was found to be dominated by linear effects in the film. The percentage change in transmission was 15% for electro-optic and 30% for electroabsorption modulation at an rms drive voltage of 53 V. The effective linear electro-optic coefficient of the LB film was 13 pm V(-1) at 633 nm for s-polarized light. We believe that this is the highest value reported to date for thick LB films.
