ABSTRACT:
An environmentally protected integrated optical component and its production process is disclosed. The component has at least one cavity (26a) isolated from the environment formed in at least one light guide layer (16, 18), with the cavity being filled with a fluid or a polymer (27) having a refractive index which is different or which can be made different from the refractive index of the layer. In particular, the cavity is filled with air. The component can be a splitting plate, a mirror, a grating, a microguide or a lens.
