Disclosed is an optical component for applications in integrated optics, including a substrate that supports a stack of three polymer layers: a lower layer deposited on the substrate, a central layer and an upper layer, the lower and upper layers having optical indices smaller than that of the central layer which is electrooptical and designed to convey a light beam, the lower layer or the upper layer possessing zones having indices of different values to create a zone of confinement of the light beam in the central layer.
