| Popis: |
We report electro-absorption studies on poly(2,5-thienylene vinylene). The response to the applied electric field, with a peak electro-absorption of 130 cm-1 at 100 kV cm-1, is comparable in magnitude to that in trans-polyacetylene and represents a substantial electro-optic nonlinearity. The electromodulation data closely resemble the second derivative of the unperturbed absorption spectrum. Using Kramers-Kronig relations we have calculated the corresponding field dependent change in refractive index. Comparison with related conjugated materials is made. |
