| Zusammenfassung: | DE 3337492 A UPAB: 19930925 Device, with a light wave guiding layer of orientation in the propagation direction of the guided light wave which leads to addn. of the Pockels and Kerr effects, has a transparent mixed crystal layer with a band gap Eg which is so high compared with the photon energy Eph that no observable electro-absorption occurs. Also claimed is use of the device as an electro-optical modulator. ADVANTAGE - The guided light wave is electrically influenced by control of amplitude-independent parameters, such as phase position and polarisation direction, rather than the amplitude, without leaving the transparent regime. 0/3 |
