Abstract
This invention relates to an integrated optics component including at least one optical guide core (11) and at least one optical cladding (9) in a substrate (7), the core and the cladding being independent of each other in the substrate, at least one portion of said cladding surrounding at least one portion of said core so as to define at least one so-called interaction area (20) between the core and the cladding, the refraction index of the cladding is different from the refraction index of the substrate and is less than the refraction index of the core at least in the part of the cladding close to the core and at least in the interaction area, a light wave possibly being introduced into said area through the core and/or the cladding. The invention is used for applications particularly in the domain of optical telecommunications, for example to make a spectral or spatial filter or a Mach-Zehnder type interferometer, or a temperature sensor.
