摘要： Tunable add/drop optical device for injecting or extracting (add/drop) at least a selected optical channel or carrier wavelength in or from a set of multiplexed channels or carriers of different wavelengths comprising a plurality of directional couplers (AD1 . . . AD6) and a plurality of phase-shift stages (SF1 . . . SF5) alternately connected in cascade, wherein each phase-shift stage defines a certain optical path length difference (&Dgr;L1 . . . &Dgr;L5) between two distinct optical paths of the stage. The tuning is performed modifying the refraction index of one path of said phase shift stages by means of Joule effect heating strips (L1 . . . L5) or by means of metallic field plates adapted to receive a signal suitable to modify the electric field intensity. The first two phase-shift stages of said plurality of phase-shift stages have differences of length of optical paths different from each other and in a preestablished ratio while the remaining phase-shift stages have differences of length of optical paths identical. It is thus possible to provide a device having an exceptionally flat cross response characteristic, substantially free of ripple due to an inevitable truncation of the Fourier expansion series.

摘要： The invention relates to a process for manufacturing an integrated optical device comprising the deposition on a support substrate of a multilayer being formed by first and second cladding layers in order to hold in a multilayer first region a waveguide core layer. The core is provided with an electromagnetic radiation (L) inlet/outlet port. Furthermore, the process provides for the formation of a regulation layer having a first etching speed associated therewith, which is distinguished from the etching speeds of the cladding layers. Subsequently to an etching of a multilayer second region, a cavity is obtained having a first wall which is inclined relative to the substrate at least partially extending in said first region and which is near said inlet/outlet port. Such etching removes portions of the regulation layer and the cladding layers at different speeds in order to result in the formation of the inclined wall.
