ABSTRACT:
The electro-optical switch according to the invention is formed by parts of two guides made of a ferro-electric material previously polarized in a suitable fashion, enclosed between two electrodes; the application of a voltage between the two electrodes has the effect of varying the refractive index of each of the guides in relation to the other and, consequently, of making it possible to enable or inhibit energy coupling between the two guides. Such a device is applicable in particular to integrated optical circuits.
