| 摘 要： | Electro-optical composites based on the product of electro-strictive and elasto-optical effects are developed.Layered composites of PbZr 1 x Ti x O 3 and polycarbonate are synthesised.Their electro-optical properties are studied.The nominal transverse electro-optical coefficient of the composite is observed to be about 3.6 times larger than that of LiNbO 3.Experiments and theoretical analyses show that the electro-optical effect of the composite has a strong ’size effect’.With the ratio of thickness/length decreasing or the width of elasto-optical phase increasing,the half-wave electric field intensity increases but the transverse electro-optical coefficient decreases for the layered composite.

| Abstract: | Electro--optical composites based on the product of electro--strictive and elasto--optical effects are developed. Layered composites of PbZr1-xTixO3 and polycarbonate are synthesised. Their electro--optical properties are studied. The nominal transverse electro--optical coefficient of the composite is observed to be about 3.6 times larger than that of LiNbO3. Experiments and theoretical analyses show that the electro--optical effect of the composite has a strong `size effect'. With the ratio of thickness/length decreasing or the width of elasto--optical phase increasing, the half-wave electric field intensity increases but the transverse electro--optical coefficient decreases for the layered composite. |
