Abstract :
A new configuration for an electro-optic waveguide phase modulator, using electrodes transversely arranged on either side of a very thin substrate is described. The device has been tested with both titanium-indiffused and proton-exchanged waveguides in lithium niobate and used to estimate the electro-optic coefficients in the guides. Photorefractive effects have been observed in well-annealed single-mode proton-exchanged waveguides at moderate power densities at lambda =0.6328 mu m.
