Abstract: Improved optical interferometric modulators have a small waveguide spacing so that the waveguide pair are close to the central electrode, to enhance electro-optic interaction. Asymmetric waveguides with differential indices are used to effectively de-couple the waveguide pair. Multiple sections of asymmetric waveguide pairs with alternating differential indices are used to achieve chirp-free operation. Another version of the device utilizes transmission-line electrode that weave closer to one of the waveguide pair alternately between sections. Another version of the device utilizes waveguide structure that one of the waveguide is closer to the central electrode in alternate section. To improve efficiency further, a DC bias is provided on the outer electrodes configured as an RF-ground but DC-float electrodes. Another improvement is to have a slot is cut underneath the waveguide region to effectively reduce to thickness of the substrate. These improvements lead to higher modulator efficiency.

Abstract: 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.
