Optical intensity modulation has been demonstrated through switching the optical beam between the main core waveguide and a closely attached leaky slab waveguide by applying a low-voltage electrical field. Theory for simulating such an LiNb slab-coupled waveguide structure was suggested, and the result indicates the possibility of making the spatial guiding mode large, circular and symmetric, which further allows the potential to significantly reduce the coupling losses with adjacent lasers and optical networks. Optical intensity modulation using electro-optic effect was experimentally demonstrated in a 5 cm long waveguide fabricated by using a procedure of soft proton exchange and then an overgrowth of thin LN film on top of a c-cut LiNb wafer.

ABSTRACTIn Integrated Optics (10), LiNbO3 is a well known material, widely used to realize very efficient electro-optic integrated devices for telecommunications such as phase modulators, intensity modulators and directional couplers. But, with the availability of good quality rare earth doped material and the perfecting of a new waveguide fabrication technique, Proton Exchange (PE), a completely different set of active devices are now possible. The common factor of these devices is that they take advantage of the high optical power resistance of the PE waveguides, of the amplification due to the rare earths, and, of the electro-optic/nonlinear properties of the crystal. In this paper we shall present such devices we have demonstrated in collaboration with the Central Research Laboratory of Thomson CSF and the Ecole Nationale Supérieure de Physique de Marseille.:-an optically pumped CW amplifier in Nd:MgO:LiNbO3 offering up to 8 dB small signal gain at δ = 1.085μm-an optically pumped CW laser in Nd:MgO:LiNbO3 emitting 14 mW at X = 1.085μm with a slope efficiency of 34% and a threshold of 2.7 mW-an FM Mode-locked waveguide laser in Nd:MgO:LiNbO3 realized by electro-optically driving the laser at the cavity round-trip frequency emitting 8 ps pulses of 250 mW peak power with a 6.2 GHz repetition rate-a self doubled waveguide laser in Nd:MgO:LiNbO3 emitting some hundreds of μW in the blue (SHG of the pump and mixing the pump with the laser frequency) and the green (SHG of the laser wavelength).
