A component, device and improved electro-optical modulation system for increasing compactness, favouring the adaptation of optical and electrical waves, and a method of fabrication. Such a component exhibits a waveguide architecture devised so that the length of the path followed by the luminous flux exhibits, with the length of the path traversed by the electrical control signal, a determined difference for decreasing or compensating for the difference in the speeds of propagation of the luminous flux and of the electrical signal. In particular, the modulation zone includes a path of the luminous flux winding around itself and successively crossing at least two indentations emanating from at least two of these control elements. It thus exhibits a length greater than that traversed by the electrical signal, for example between a first and a second region of interaction between this control signal and this luminous flux.
