摘要：
Measurements of electrooptic modulation of surface plasmon resonance have been carried out on horizontally transferred Langmuir-Blodgett films of 2-(docosylamino)-5-nitropyridine. The observed Pockels response is approximately constant for different numbers of layers in multilayered films and is proportional to the strength of the modulating field. The calculated second-order susceptibility values are approximately 2 x 10(-13) m V-1, 2 orders of magnitude lower than those derived from second harmonic generation studies. The presence of the Pockels effect is attributed to off-diagonal terms in the second-order susceptibility.
