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.
报道了利用基于朗缪尔-布洛杰特（LB）膜的法布里-珀罗标准具进行电光和电吸收调制。发现调制主要由膜中的线性效应主导。在均方根驱动电压为53 V时，电光调制的透射率变化百分比为15%，电吸收调制为30%。对于s偏振光，LB膜在633 nm处的有效线性电光系数为13 pm V⁻¹。我们认为这是迄今为止报道的厚LB膜的最高值。
