Beschreibung
Zusammenfassung:	An optoelectronic-RF device has at least one optical modulator/sensor comprising at least two cascaded optical-waveguide gratings and at least one non-grating optical waveguide segment interconnecting the at least two cascaded optical-waveguide gratings, with at least one optical waveguide segment interconnecting the at least two cascaded optical-waveguide gratings via the at least one non-grating optical waveguide segment. An RF waveguide is provided for propagating an RF electric field, the at least one optical modulator/sensor being disposed in and forming a portion of the RF waveguide with light propagating through the cascaded optical-waveguide gratings in a direction that is perpendicular to a direction of propagation of the RF electric field in the RF waveguide.
