Abstract: A diffraction grating for a waveguide or for externally incident light. The grating includes a substrate and an electrooptic structure extending over it. The electrooptic structure may include a waveguide having a propagation axis. A first and a second electrode structure are provided on either side of the electrooptic structure so that an electric field is generated in the electrooptic structure when a potential is applied to the electrodes. The first electrode structure has an interdigitated configuration defining a plurality of fingers. In use, respective potentials V0 and V0+&Dgr;V are applied to adjacent fingers. The diffraction grating induced in the electrooptic structure by the periodic electric field advantageously has a refractive index adjustable by varying V0 and &Dgr;V and a spatial periodicity adjustable by varying &Dgr;V.

Abstract: The present invention relates generally to an apparatus that increases the conversion efficiency of optical parametric oscillators and also reduces overall system size and susceptibility to vibration. The first embodiment of the present invention incorporates a PPLN OPO architecture (20) which includes mirrored coatings (32, 36) on the entry surface area (22) and exit surface area (24) of a monolithic nonlinear optical medium (26). The coatings (32, 36) act as mirrors, however, the mirrors are actually affixed to the PPLN element (28, 30). In the first embodiment of the present invention, the PPLN element (26) is a dual grated element. The second embodiment of the present invention uses a single grated PPLN element.
