Paper Abstract

The fabrication of a phase modulator using transverse electrodes on a thin z-cut lithium niobate substrate is described. The modulator has an overlap integral of unity, allowing accurate measurement of the electrooptic coefficients and providing a low operating voltage. The device has been tested with both titanium-indiffused and proton-exchanged waveguides and used to estimate the electrooptic coefficients in the guides. The reappearance of the photorefractive effect is also reported in single-mode proton-exchanged waveguides fabricated using a dilute melt and annealing to restore the electrooptic effect.
