Abstract: A method is provided of fabricating integrated optical devices on a starting substrate by means of fieldassisted ion exchange. The prepared substrate is connected to a source of potential difference, is masked in accordance with the optical circuit to be implemented and is dipped in a melted salt providing an ion source for the exchange process, a further electrode applying an electric field for inducing ion exchange.

Abstract: A method of adjusting the operation characteristics of integrated optical devices, allowing a considerable number of out-of-tolerace devices to be recovered by depositing on the surface whereupon the optical guides are manufactured, once the normal fabrication process is completed, a further layer of transparent material with suitable size and refractive index (SA).

Abstract: Apparatus for measuring the effective refractive index in optical fibres, in which a source (1) sends light radiations, the wavelength of which can be varied within a predetermined interval, into a fibre span (2), and a detector (5) collects the radiation outgoing from the span (2) and is connected with means (6, 7) for measuring the intensity of the radiation collected by the detector as the wavelength varies, in order to determine the oscillation period of the fibre transmittance or reflectivity and to obtain the effective refractive index from such period.
